How does Peter go from telling Jesus he’d die for Him, and later while trying to defend Jesus from his captors,  cutting off the ear of someone who was there to arrest Jesus – to 44 years later asleep in a prison cell chained to two guards the night before he was to be executed? How do you go from feeling like you need to conquer the world by exerting your voice or strength to being at peace with whatever life bring your way? In Peter’s life, we see that real spiritual maturity is measured in depth of surrender and expressed in obedience, not in hype or overconfidence. Spiritual maturity isn’t measured in how many bible verses you can quote, it is measured in how you die to yourself.
