Faithfulness hinges upon what we value as important combined with commitment. Humans have a powerful tendency to be faithful to what they think is truly important, be it a family name, spouse, friendship, employer, school, athletic team, or even certain things like a make of automobile.
This tendency was an issue when the disciples decided to follow Peter's lead and return to their fishing trade after Jesus' death and resurrection. In John 21:15-17, Jesus pointedly asks Peter three times whether he loved Him. The first time He asks whether he loved Him "more than these," referring either to his fellow apostles or the tools of his fishing trade. The implication is inescapable: Jesus wanted Peter to hold Him of greater importance than anything on earth. Considering Peter's weighty responsibility, he could not be faithful to Jesus without the staunchest commitment to Him as most important of all in his life.
The meaning to us is clear. We must love Christ supremely, or we do not love Him much if at all. If we are not willing to give up all earthly possessions, forsake all earthly friends, and obey Him above all others—including our own carnal desires—to be faithful to Him, our attachment to Him is tenuous at best. Is such a proposition too much? Does not marriage require a similar faithfulness from each spouse? Without it, it is no wonder there is so much adultery and divorce.
Holding true to the course God has laid before us is difficult amid this world's many alluring distractions clamoring for our time and attention. This world is attractive to human nature and bids us to expend our energies in self-satisfaction. Jesus warns all who take up their cross that the way is difficult and narrow, requiring a great deal of vision and discipline to be faithful to His cause. Some have completed the course. Those who held God and His way in the highest esteem in their lives are awaiting those of us traveling the path now. Will we be faithful as they were?
