I am just cautioning you. You say that God was not tempted. Yet we can read For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet without sin.[Hebrews 4:15] This is why we have to compare scripture with scripture, not pit it against itself. We can also read Let no one say when he is tempted, “I am being tempted by God”; for God cannot be tempted by evil, and He Himself does not tempt anyone.[James 1:13] The only logical conclusions that can be made by comparing these two verses is 1) the Christ is not God, 2) God in James 1:13 is referring to God the Father, or 3) either the writer of Hebrews or James is off in their writing.
When we read He said, “Do not stretch out your hand against the lad, and do nothing to him; for now I know that you fear God, since you have not withheld your son, your only son, from Me.”[Genesis 22:12] The reason I bring this verse into the discussion is open theists use this verse to say God does not know things until they unfold before Him. However, the saying 'now I know' is the same as A man of sorrows and acquainted with grief;[Isaiah 53:3] What was meant by this is that God became acquainted with grief the same way Abraham was as he was drawing the knife back to sacrifice his own son. The Christ was tempted the same exact way we are, and He became acquainted with our own temptations. The same word used for 'know' is the same word used for 'acquainted'. Its the Hebrew word yada which has a wide semantic range.
So, God the Son was tempted, but God the Father was not. That is why understanding there is a Triune God is imperative to understanding things like these.
