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.
Have you ever been afraid to try again because your past attempts didn't work out well? Are you trusting more in your track record than God, who has the power to move on your behalf?
