David said to Achish, Therefore you shall know what your servant will do. Achish said to David, Therefore will I make you keeper of my head for ever.
This whole pericope illustrates that, when opposition from ungodly people persists, God’s people should continue to pray and trust Him for protection rather than taking matters into their own hands. If we initiate a plan without seeking God’s guidance, we may remove one source of aggravation and danger only to find ourselves in another. Such plans may result in some good, but they may also put us in situations where we find it even more tempting to disobey God (cf. Jacob). We should, instead, remember God’s promises (e.g., 1 Peter 1:3-9; 2 Peter 1:2-4) and pray for His guidance (cf. Philippians 4:6-7).
