(Proverbs 7:9 KJV) In the twilight, in the evening, in the black and dark night:
This is a reminder that God is aware of all we do. We can’t hide. We can’t run. He knows.
So? Your mother may have times when she isn’t looking. You may be able to get away with what is on your mind in regard to her. God, on the other hand, is always aware. File that away next time you look both ways.
