Prodigal son
The son represents someone living in rebellion toward God. The father represents God who waits patiently, waiting to restore us when we return to Him with a humble heart. God is waiting with compassion for one to return.
The picture of the father receiving the son back into a relationship is a picture of how we should respond to repentant sinners as well (1 John 4:20-21; Luke 17:3; Galatians 6:1; James 5:19-20). “All have sinned and fall short of the glory of God” (Romans 3:23). We are included in that “all,” and we must remember that “all our righteous acts are like filthy rags” apart from Christ (Isaiah 64:6; John 15:1-6). It is only by God’s grace that we are saved, not by works that we may boast of (Ephesians 2:9; Romans 9:16; Psalm 51:5). That is the core message of the Parable of the Prodigal Son.
