“Look upon mine affliction and my pain .…” Psalm 25:18
In Psalm 25, David points God to his affliction and his pain. It is striking that in this verse David does not ask God to take away his affliction and pain, but to take away his sins.
“… and forgive all my sins.”
So David realizes that his affliction and pain are related to his sins.
In this Psalm David repeatedly asks for His truth, to learn His truth:
in thy truth, and teach me” Psalm 25:5
“Shew me thy ways, O LORD; teach me thy paths.” Psalm 25:4 (see also Isaiah 55:8)
“Good and upright is the LORD: therefore will he teach sinners in the way.” Psalm 25:8
“The meek will he guide in judgment: and the meek will he teach his way.” Psalm 25:9
“What man is he that feareth the LORD? him shall he teach in the way that he shall choose.” Psalm 25:12
We need to be taught His truth to get rid of our sins. Because sin is lies and delusions (imaginations of the thoughts of the heart of man) (Genesis 6:5).
“Redeem Israel, O God, out of all his troubles.” Psalm 25:22
