Acts‬ ‭13:22‬ ‭NKJV‬‬

“And when He had removed him, He raised up for them David as king, to whom also He gave testimony and said, ‘I have found David the son of Jesse, a man after My own heart, who will do all My will.’”

God found something in the heart of David that He didn’t find in the heart of anybody else around him which earned David his title as ‘man after God’s heart’.

So what did God see in David’s heart?
