Read Psalm 69.
Please read it again considering these things:
It is mainly a prophetic Psalm, describing what Christ experienced. You can verify this by reading the Gospels, Matthew, Mark, Luke, John.
THINK how foolish we are to ever assume the Lord Jesus Christ doesn’t know what we are experiencing. THINK how insulting to him to assume he can’t understand.
Now, take whatever it is that is hanging you up to the Lord in prayer. Thank him for listening and thank him that his grace is sufficient for you in every situation. He will see you through. ASK HIM.
