There are several references to eternal life in scripture.
27 Then Peter answered and said to Him, "See, we have left all and followed You. Therefore what shall we have?" 28 So Jesus said to them, "Assuredly I say to you, that in the regeneration, when the Son of Man sits on the throne of His glory, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel. 29 And everyone who has left houses or brothers or sisters or father or mother or wife or children or lands, for My name's sake, shall receive a hundredfold, and inherit eternal life. 30 But many who are first will be last, and the last first.
31 "When the Son of Man comes in His glory, and all the holy angels with Him, then He will sit on the throne of His glory. 32 All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats. 33 And He will set the sheep on His right hand, but the goats on the left. 34 Then the King will say to those on His right hand, 'Come, you blessed of My Father, inherit the kingdom prepared for you from the foundation of the world: 35 for I was hungry and you gave Me food; I was thirsty and you gave Me drink; I was a stranger and you took Me in; 36 I was naked and you clothed Me; I was sick and you visited Me; I was in prison and you came to Me.' 37 "Then the righteous will answer Him, saying, 'Lord, when did we see You hungry and feed You, or thirsty and give You drink? 38 When did we see You a stranger and take You in, or naked and clothe You? 39 Or when did we see You sick, or in prison, and come to You?' 40 "And the King will answer and say to them, 'Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me.' 41 "Then He will also say to those on the left hand, 'Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels: 42 for I was hungry and you gave Me no food; I was thirsty and you gave Me no drink; 43 I was a stranger and you did not take Me in, naked and you did not clothe Me, sick and in prison and you did not visit Me.' 44 "Then they also will answer Him, saying, 'Lord, when did we see You hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to You?' 45 "Then He will answer them, saying, 'Assuredly, I say to you, inasmuch as you did not do it to one of the least of these, you did not do it to Me.' 46 "And these will go away into everlasting punishment, but the righteous into eternal life." NKJV
17 Now as He was going out on the road, one came running, knelt before Him, and asked Him, "Good Teacher, what shall I do that I may inherit eternal life?" 18 So Jesus said to him, "Why do you call Me good? No one is good but One, that is, God. 19 You know the commandments: 'Do not commit adultery,' 'Do not murder,' 'Do not steal,' 'Do not bear false witness,' 'Do not defraud,' 'Honor your father and your mother.' "
27 My sheep hear My voice, and I know them, and they follow Me. 28 And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. 29 My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father's hand. NKJV
23 Then Jesus looked around and said to His disciples, "How hard it is for those who have riches to enter the kingdom of God!" 24 And the disciples were astonished at His words. But Jesus answered again and said to them, "Children, how hard it is for those who trust in riches to enter the kingdom of God! 25 It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God." 26 And they were greatly astonished, saying among themselves, "Who then can be saved?" 27 But Jesus looked at them and said, "With men it is impossible, but not with God; for with God all things are possible." 28 Then Peter began to say to Him, "See, we have left all and followed You." 29 So Jesus answered and said, "Assuredly, I say to you, there is no one who has left house or brothers or sisters or father or mother or wife or children or lands, for My sake and the gospel's, 30 who shall not receive a hundredfold now in this time--houses and brothers and sisters and mothers and children and lands, with persecutions--and in the age to come, eternal life. 31 But many who are first will be last, and the last first."
13 No one has ascended to heaven but He who came down from heaven, that is, the Son of Man who is in heaven. 14 And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, 15 that whoever believes in Him should not perish but have eternal life. 16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. 17 For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
34 Jesus said to them, "My food is to do the will of Him who sent Me, and to finish His work. 35 Do you not say, 'There are still four months and then comes the harvest'? Behold, I say to you, lift up your eyes and look at the fields, for they are already white for harvest! 36 And he who reaps receives wages, and gathers fruit for eternal life, that both he who sows and he who reaps may rejoice together.
54 Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. 55 For My flesh is food indeed, and My blood is drink indeed. 56 He who eats My flesh and drinks My blood abides in Me, and I in him. 57 As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. 58 This is the bread which came down from heaven--not as your fathers ate the manna, and are dead. He who eats this bread will live forever." 59 These things He said in the synagogue as He taught in Capernaum. 60 Therefore many of His disciples, when they heard this, said, "This is a hard saying; who can understand it?" 61 When Jesus knew in Himself that His disciples complained about this, He said to them, "Does this offend you? 62 What then if you should see the Son of Man ascend where He was before? 63 It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life. 64 But there are some of you who do not believe." For Jesus knew from the beginning who they were who did not believe, and who would betray Him. 65 And He said, "Therefore I have said to you that no one can come to Me unless it has been granted to him by My Father." 66 From that time many of His disciples went back and walked with Him no more. 67 Then Jesus said to the twelve, "Do you also want to go away?" 68 But Simon Peter answered Him, "Lord, to whom shall we go? You have the words of eternal life.
27 My sheep hear My voice, and I know them, and they follow Me. 28 And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
24 Most assuredly, I say to you, unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain. 25 He who loves his life will lose it, and he who hates his life in this world will keep it for eternal life. 26 If anyone serves Me, let him follow Me; and where I am, there My servant will be also. If anyone serves Me, him My Father will honor.
17:1 Jesus spoke these words, lifted up His eyes to heaven, and said: "Father, the hour has come. Glorify Your Son, that Your Son also may glorify You, 2 as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him. 3 And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
...God, 6 who "will render to each one according to his deeds": 7 eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality;
21 so that as sin reigned in death, even so grace might reign through righteousness to eternal life through Jesus Christ our Lord.
23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
1 Timothy 6:12-19
12 Fight the good fight of faith, lay hold on eternal life, to which you were also called and have confessed the good confession in the presence of many witnesses. 13 I urge you in the sight of God who gives life to all things, and before Christ Jesus who witnessed the good confession before Pontius Pilate, 14 that you keep this commandment without spot, blameless until our Lord Jesus Christ's appearing, 15 which He will manifest in His own time, He who is the blessed and only Potentate, the King of kings and Lord of lords, 16 who alone has immortality, dwelling in unapproachable light, whom no man has seen or can see, to whom be honor and everlasting power. Amen. 17 Command those who are rich in this present age not to be haughty, nor to trust in uncertain riches but in the living God, who gives us richly all things to enjoy. 18 Let them do good, that they be rich in good works, ready to give, willing to share, 19 storing up for themselves a good foundation for the time to come, that they may lay hold on eternal life.
1:1 Paul, a bondservant of God and an apostle of Jesus Christ, according to the faith of God's elect and the acknowledgment of the truth which accords with godliness, 2 in hope of eternal life which God, who cannot lie, promised before time began, 3 but has in due time manifested His word through preaching, which was committed to me according to the commandment of God our Savior;
4 But when the kindness and the love of God our Savior toward man appeared, 5 not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, 6 whom He poured out on us abundantly through Jesus Christ our Savior, 7 that having been justified by His grace we should become heirs according to the hope of eternal life.
1 John 1:1-4
1:1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, concerning the Word of life-- 2 the life was manifested, and we have seen, and bear witness, and declare to you that eternal life which was with the Father and was manifested to us-- 3 that which we have seen and heard we declare to you, that you also may have fellowship with us; and truly our fellowship is with the Father and with His Son Jesus Christ. 4 And these things we write to you that your joy may be full.
1 John 2:25
25 And this is the promise that He has promised us--eternal life.
1 John 5:11-13
11 And this is the testimony: that God has given us eternal life, and this life is in His Son. 12 He who has the Son has life; he who does not have the Son of God does not have life. 13 These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life and that you may continue to believe in the name of the Son of God.
1 John 5:20
20 And we know that the Son of God has come and has given us an understanding, that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
20 But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit, 21 keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
