Every believer battling temptation faces an inward struggle. A part of him (his spirit) wants to do right and to please the Lord, while another part of him (his flesh) loves sin and self more than the Saviour. If this struggle goes unchecked, the flesh will certainly win every time. Man’s spirit requires reinforcements in order to win this battle. According to Matthew 26:41, two of these resources include watchfulness and prayer. It is imperative for each believer to implement both, for one without the other leaves a person with certain vulnerabilities when temptations arise. Watchfulness demonstrates the saint’s personal responsibility, while prayer demonstrates his need for God’s intervention.
When one side defeats another in battle, to the victor goes the spoils. This means that the victor enters the camp of the defeated and takes its valuable possessions (including women, children, material goods, etc.). With this truth in mind, the apostle Paul warned the believers at Colosse to be on guard, knowing that men would seek to spoil them through philosophy and vain deceit. In other words, accepting the philosophies of men, or false doctrines, is likened to losing a battle and allowing the enemy to rob the believer of his most valuable possessions. It is important to understand that although a believer can never lose his salvation, he can be robbed of his stability, growth, peace, and joy.
