Firstly, the idea that "the sins we commit now go back to be absorbed by Christ" connects with the belief in Christ's timeless sacrifice. According to Christian doctrine, Jesus Christ's sacrifice on the cross is sufficient for the redemption of all sins—past, present, and future. Hebrews 10:12 says, "But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God." This suggests a theological interpretation that Christ's sacrifice transcends time, offering redemption for sins across all eras.
Regarding the question of praying for someone who has already died, the Bible does not provide explicit instructions or examples of praying for the dead to affect their salvation posthumously. The scriptural emphasis is generally on the living making decisions for Christ. Hebrews 9:27 states, "And just as it is appointed for man to die once, and after that comes judgment," implying that after death, one's eternal fate is decided. However, interpretations vary, and some traditions within Christianity do practice prayers for the departed, hoping for their peace and rest.
The statement that "I believe that the God Adam and Eve spoke to was Yeshua, because he is the human form of God" is a thoughtful conjecture but not directly supported by biblical texts. The Bible does not explicitly state the physical manifestation of God who walked with Adam and Eve in the Garden of Eden (Genesis 3:8). While Christians believe that Jesus Christ (Yeshua) is God incarnate (John 1:14), his incarnation is understood to have occurred in the New Testament, born of the Virgin Mary. The Old Testament appearances of God, sometimes referred to as theophanies, are not explicitly identified as the pre-incarnate Christ, though some theologians have speculated on this possibility.
