What does it mean to live out your faith in the world around you? It's not easy, and Peter recognizes it. While there are so many forces out in the world and within (through our carnal nature) that wage war against your soul - like an evil assassin that enters your "fort" trying to tear apart your faith, there are also many elements out there to keep it strong and healthy. Peter knows a thing or two about being weak, carnal, and stupid. In fact, for a time, Peter was a "slacker", While Peter was built up in Christ, he knew that Christians can be backslidden. However, there is a day coming soon that Christ is going to visit us. The question to ask ourselves then would be; will he be proud of us?
