What does it mean when the Bible says God repented?

The use of the term 'repented' concerning God, as seen in 1 Samuel 15:11, should be understood in the context of anthropomorphism, where human emotions are attributed to God to convey His response to human actions. God does not change or make mistakes (Malachi 3:6); instead, this language allows humans to comprehend God's holiness and the gravity of sin. The 'repentance' indicates a shift in God's dealings rather than a change in His character or intentions. It underscores the seriousness of Saul's disobedience and serves as a sobering reminder of the consequences when one strays from obedience to God's commands.
