Questionable

(Psa 43:2 KJV)  For thou art the God of my strength: why dost thou cast me off? why go I mourning because of the oppression of the enemy?

(Proverbs 26 also read)

Good question.  I can think of many possible answers such as rebellion and a refusal to repent, but that is not the answer given here.  If you read the context I hope you will get the impression that God has not really “rejected” (2186a) the author as much as the man is simply not paying attention.  God can turn His back on us but that is not the case when we honestly seek Him.

Notice I had the squish word “honestly”.  Keep in mind that God can see our hearts and read our minds.  He isn’t like the high school counselor who mainly sees what he wants to see or is fooled by your play acting.

So?  God did not reject Him.  He ignored, or rejected, God.  Understand the difference.
