What does the Bible say about a man after God's own heart?

In Acts 13:22, God Himself testifies that David is a man after His own heart, which highlights the relational aspect of obedience and alignment with God's desires. This designation is not merely for David; it reflects the transformation given to all believers through the new birth. Every believer, like David, is called a man or woman after God’s own heart because they have received a heart that beats in tune with God's will. Thus, being after God’s own heart means pursuing God's glory and fulfilling His will, which is central to the identity of all who are saved.
