OK, we'll take this a step at a time.

When God told Adam:

but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die.” (Genesis 2:17)

Did Adam die immediately after he ate the fruit? And if not, did God lie to Adam when He told him that if he ate the fruit he would die?

Did Adam die immediately after he ate the fruit? And if not, did God lie to Adam when He told him that if he ate the fruit he would die?

No to the second question. Adam's death is not mentioned until Genesis 5. Since he did not die physically, some say that he must have died spiritually in order to meet the "in the day" requirement. Perhaps a day is like a thousand years. I really do not have the answer to your question but I will point out the weakness of trying to interpret it as a spiritual death in order to make it immediate.

As I have stated before, there is support for the idea that spiritual death is the second death spoken of in Revelation 20. Scripture is arranged perfectly as we expect considering that God is the author. You cannot change the order of things without support of other scripture or nature. Birth will always come before death and resurrection cannot happen until after death. That which is natural precedes that which is spiritual.

We are created in Adam, the natural man, first. Next we are created in Christ, the spiritual man (Ephesians 2:10). The first creation is a picture of the second. That which is invisible is clearly seen. Christ is created in Adam and Adam is created in Christ.

Do you believe that Old Testament saints must be born again? (second or spiritual birth) If so, when might it have happened to Adam? The doctrine of eternal security may apply.
