Confessing and renouncing evil opens the hand to God. The truth will set you free. The open hand is friendly, as in a hand shake. A sign of peace, justice, and love. Be flexible and open.
Rebellion is ugly.
We must treat all of life with an open hand. To hold all that God has given us in an open hand. Free to give, free to receive. Without complaint, without grumbling. To close your hand to God is a bad thing.
