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.
Every unsaved person will have windows of opportunities when he becomes most receptive to the gospel of Christ. The Devil works hard to keep people in darkness and will distract them by every means necessary (i.e., the death of a loved one, a crying child, a ringing phone, busyness, etc.). The salvation of a soul involves a spiritual battle that can only be won by the Lord’s intervention. There is a window of time when the lost are most receptive to the gospel, likewise suggesting only a window of opportunity for the saved to speak for Christ. This is the very reason the apostle Paul stressed the importance of the saints of God beseeching the Lord to open to them a door of utterance (Ephesians 6:19).
