What does the Bible say about reconciliation with God's will?

In 2 Samuel 3, Abner's reconciliation to David symbolizes how God reconciles sinners to His will. Initially opposed to David, Abner comes to recognize David as the rightful king, which reflects the believer's journey of being reconciled to God through grace. Romans 10:9 indicates that if we confess with our mouth Jesus as Lord and believe in our hearts that God raised Him, we will be saved. This transformation is a work of God's grace, granting us the faith necessary to believe and confess Him as our Savior.
