Jesus asked Peter to demonstrate his love by serving and feeding people. This is the ultimate way to show love towards God, not by expecting to be served. Peter understood this and was commissioned by Jesus, transforming his life. To abide in God, we must come to the end of ourselves and present ourselves as living sacrifices before him. When we cast our will before Him, He will prepare our ways and steps.
