Being successful in life, employment, public office, Christian service requires commitment.
John 6:66-69 is an example of how a leader deals with his followers when he sees they lack commitment.
Peter shows an example of showing leadership of a committed group.
Commitment is entrusting something of value to another person. It is obligating yourself to a particular act or action. The real measure and evidence of your commitment is your action, as the result of your act of commitment.
Real commitment starts in the heart and characterizes our relationship with God.
