Jesus' Definition of Eternal Life's Requirements in Scripture
Jesus' Definition of Eternal Life
The Greek phrase "ζωὴ αἰώνιος" (zōē aiōnios), or "eternal life," is a central concept in Jesus' teachings. According to John 17:3, Jesus defines eternal life as knowing God and Christ [8]. This definition is rooted in the Hebrew concept of "חַיִּים" (chayyim), or "life," which encompasses not just physical existence but also a deep, spiritual relationship with God [5].
In John 6:35, Jesus declares, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst" [7]. This statement is closely tied to his definition of eternal life, as it emphasizes the importance of faith in him for spiritual sustenance. Jesus further explains that his commandment is eternal life, and that those who believe in him will have life (John 12:50) [6].
The requirements for eternal life, as outlined by Jesus, include believing in him and following his commandments. In John 3:15, Jesus states that "whoever believes in him shall have eternal life" [9]. This is reinforced in 1 John 2:25, where it is written that "this is the promise which He Himself made to us: eternal life" [3, 4].
The biblical concept of eternal life is not limited to the New Testament. In the Old Testament, the idea of eternal life is foreshadowed in Daniel 12:2, where it is written that "many of those who sleep in the dust of the earth shall awake, some to everlasting life" [1]. The Psalmist also expresses a desire to know God intimately, stating that "as for me, I shall behold your face in righteousness; when I awake, I shall be satisfied with your likeness" (Psalm 17:15).
The various traditions represented in the sources agree that eternal life is a gift from God, received through faith in Jesus Christ. According to John Gill, eternal life is "a pure free grace gift of God the Father, proceeding from his sovereign good will and pleasure" [11]. Adam Clarke notes that the person who is saved is "drawn by the Father; hears his instructions; accepts the salvation offered; is given to Christ Jesus, that he may be justified by faith; is nourished by the bread of life; perseveres in the faith; is not lost, but is raised up at the last day; and is made a partaker of eternal life" [10].
The biblical understanding of eternal life is closely tied to the concept of immortality, which is taught in both the Old and New Testaments [2]. The doctrine of immortality is "plainly implied in the writings of Moses" and is more fully developed in the later books of the Old Testament [2].

- Easton's Bible Dictionary “Easton's Bible Dictionary: Eternal life — This expression occurs in the Old Testament only in Dan. 12:2 (R.V., "everlasting life"). It occurs frequently in the New Testament (Matt. 7:14; 18:8, 9; Luke 10:28; comp. 18:18). It comprises the whole future of the redeemed (Luke 16:9), and is opposed to "eternal punishment" (Matt. 19:29; 25:46). It is the final reward and glory into which the children of God enter (1 Tim. 6:12, 19; Rom. 6:22; Gal. 6:8; 1 Tim. 1:16; Rom. 5:21); their Sabbath of rest (Heb. 4:9; comp. 12:22).

- Easton's Bible Dictionary “Easton's Bible Dictionary: Immortality — Perpetuity of existence. The doctrine of immortality is taught in the Old Testament. It is plainly implied in the writings of Moses (Gen. 5:22, 24; 25:8; 37:35; 47:9; 49:29, comp. Heb. 11:13-16; Ex. 3:6, comp. Matt. 22:23). It is more clearly and fully taught in the later books (Isa. 14:9; Ps. 17:15; 49:15; 73:24). It was thus a doctrine obviously well known to the Jews. With the full revelation of the gospel this doctrine was "brought to light" (2 Tim. 1:10; 1 Cor. 15; 2 Cor. 5:1-6; 1 Thess. 4:13-18).”
