Jesus reminds us that one day everything will be revealed. God knows everything about us, but He isn't waiting to use it against us. He isn't trying to "catch us" in order to embarrass us. God wants us to turn to Him and be redeemed. God wants us to be purified through His Son. When we are living in God, according to His will, we shouldn't be afraid of having the hidden revealed!
One day everything hidden will be revealed. Trust in God's will and don't worry!
Prayer:
Dear God-
Thank You for loving me and for sending Jesus to save me from my sin. Help me to live so that I have no worries about what is said in darkness being revealed! Through Jesus, my Redeemer, I pray, amen.
