Adam and Eve
On the sixth day "God created man in His own image" (Ge 1:27) in "spirit and soul and body" (1Th 5:23). "It is I who made the earth and created man upon it" (Isa 45:12). "It was Adam who was first created" (1Ti 2:13) and in Hebrew his name means "humanity." In an extended sense the word "flesh" is also humanity. The human race inherits from Adam for, "as in Adam all" (1Co 15:22), applies to everyone. "God saw all that He had made, and behold, it was very good" (Ge 1:31). Therefore it cannot be concluded that man is inherently sinful.
When God put Adam in the Garden of Eden he "commanded the man" (Ge 2:16) "from the tree of the knowledge of good and evil you shall not eat, for in the day that you eat from it you will surely die" (:17). It was not said that "you will drop dead" as if it was poisonous. So to die must mean that death was not part of God's scheme of things, but it would transpire if Adam was disobedient. Later it happened that "every intent of the thoughts of . . . [man's] heart was only evil continually" (6:5). So God "was sorry that He had made man on the earth" (:6).
Much later John saw the "Lamb of God who takes away the sin of the world!" (Jn 1:29). Jesus "will save His people from their sins" (Mt 1:21). Your sins will be "wiped away" (Ac 3:19). How is this accomplished? It is because "Christ died for our sins" (1Co 15:3). In society there is a penalty to pay when someone has transgressed the law. It is a legal matter of "judgment" (Jn 5:24). "Without shedding of blood there is no forgiveness" (Heb 9:22). "'The life of the flesh is in the blood . . . for it is the blood by reason of the life that makes atonement'" (Lev 17:11). God anticipated this because Christ "was foreknown before the foundation of the world" (1Pe 1:20) and "His works were finished from the foundation of the world" (Heb 4:3). Therefore Christ became "the Lamb that was slain" (Rev 5:12) "through the offering of the body of Jesus Christ once for all" (Heb 10:10). Christ "gave himself as a ransom for all" (1Ti 2:6).
