In Jesus’ high priestly prayer, He defined eternal life as follows: “‘And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent’” (John 17:3). The New Testament everywhere teaches that eternal life is promised to those who believe in Jesus: “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life” (John 3:16). Those who die in the Lord and those who are serving Him when He returns will receive the reward of eternal life: “But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life. For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord” (Romans 6:22, 23).
