32 Then David said to Abigail, "Blessed be the LORD God of Israel, who sent you this day to meet me,
33 and blessed be your discernment, and blessed be you, who have kept me this day from bloodshed and from avenging myself by my own hand.
34 “Nevertheless, as the LORD God of Israel lives, who has restrained me from harming you, unless you had come quickly to meet me, surely there would not have been left to Nabal until the morning light as much as one male."
There will be some who say that Abigail made a decision of her own volition to approach David with gifts in an effort to appease his anger against her husband Nabal. David tells us otherwise in verse 32, God sent her to meet him. This is just another example of God directing the footsteps of men (and women) and working in people to will and to do according to His good pleasure (Psalm 37:23, 57:2, 138:8; Proverbs 3:5-6, 16:9, 19:21, 20:24, 21:1; Isaiah 14:27, 46:10; Jeremiah 10:23; Lamentations 2:17; Philippians 2:13), He works ALL things after the counsel of His will (Ephesians 1:11).
David was so filled with wrath against Nabal that he had in mind to kill not only Nabal but every man in Nabal’s household. He had his plan and had set it into motion, but God intervened. He not only sent Abigail to David, God also restrained David from harming Abigail too - “...who has restrained me from harming you...” God moved the king’s heart like He moves rivers of water (Proverbs 21:1).
God worked then as He does today. We do not become children of God by the will of the flesh (John 1:13).
