Listening is just as important as praying. In order to receive confirmation and instruction, we must actually pause to hear what God is saying. How silly would it be if you were to call a friend, ask them a question, and then hang up the phone before they give you an answer? That's what we do when we end our prayers before waiting for God to speak.
Peter denied the one he was so eager to protect. And Jesus was rejected by someone He was about to suffer and die for. Someone He loved. It reminds me of the times Jesus has had to watch me make poor decisions after He has already warned me. But even when we waver, God's love for us does not.
"I want you to show love, not offer sacrifices. I want you to know me more than I want burnt offerings." Hosea 6:6 (NLT)
