Have you ever been praying on something, and then God interrupted your prayer and told you to forgive someone? I have. The Lord be like “I’m really happy for you right now, and Imma let you finish, but…”.
“And when you stand praying, if you hold anything against anyone, forgive them, so that your Father in heaven may forgive you your sins.” Mark 11:25
I don’t like forgiving someone who I don’t think deserves it. But the reality is that I don’t deserve it either. If your prayers seem to be clogged up, maybe you should use the forgiveness plunger.
