Psalm 36:3 is so tragic. Listen:

“The words of his mouth are iniquity and deceit: he hath left off to be wise, and to do good.”

How did this happen!? And why?!

Someone quit being wise and quit doing good.

Can that happen to me? Very easily!

By the grace of God, I purpose to be faithful.

With His help, I will retain the wisdom I have. And I will continue to do good.

I will not go back to the old ways of thinking and living.

May I be on guard against those “little” ways in which I can stray.

Surely you could add something...
