One of my favorite characters in the Bible (besides Jesus, of course) is Peter. Peter who denied Jesus three times, Peter. After Jesus had risen, Peter was allowed three times to redeem himself and prove his love for the Lord. Peter was also among the first to see the risen Savior. I believe Jesus specifically called Peter by name to ordinate this.
I identify with Peter so much. His love for his Lord was sincere, but he denied Jesus to protect himself. I love Jesus wholeheartedly, and I like to think that if I was told to deny Christ or be killed, that I would stand strong and die for the faith, but that promise is really difficult to make unless I am actually in that situation. Regardless, God knows my heart, and he says my name. That's grace.
