Imagine the vulnerabilities of a watchman who refuses to keep his eyes open to every possible angle from which danger could arise. No doubt the enemy would scout the land observing the bad habits of the watchman. If the watchman fails to examine each point of entry, the enemy will attack from the unprotected angle. In like manner, believers are to walk circumspectly. The word circumspect means to look all around. Believers are to be sober and vigilant knowing that their enemy, the Devil, “walketh about, seeking whom he may devour” (1 Peter 5:8). God’s enemies always search for the weak spot where the hedge has been cut down or ignored. This is why there is no angle in the believer’s life that can be safely ignored.
Many Bible passages connect watchfulness and prayer. While preaching sounds the trumpet of alarm in the ears of men, prayer sounds the alarm in the ears of God. As a watchman, each believer has a responsibility to his brother or sister in Christ. While some believers are spiritually sleeping, unaware of their present danger, other believers ought to be standing upon the tower of watchfulness and calling upon the Lord. This was the point of Paul’s teaching in Ephesians 6:18 when he said, “Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints.”
On the surface, today’s passage does not offer a specific definition for the word hospitality, yet we are not left without clues. First of all, hospitality is something that is done “one to another.” This means that it is an action that should be done to other believers. It should also be done “without grudging.” Additional insight can be gleaned by considering hospitality’s root word, hospital. A basic definition for the word hospital involves a shelter for the needy or a place where the sick can recover. Thus, hospitality involves taking others in, even for a short time, to strengthen them in some area of need. Hospitality can be as simple as sharing a meal together or it may require more effort and time.
