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, compare Heb. 11:13-16; Ex. 3:6, compare 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).
