Exodus 32 reveals both the depth of human sin and the unchanging mercy of God. Israel's rebellion proves our total inability to save ourselves, yet Moses stands as a mediator, pleading for grace based on God's glory and covenant promises. His intercession foreshadows the greater work of Jesus Christ, who perfectly mediates between God and sinners through His sacrificial death and continual intercession. Prayer, rightly understood, does not change God's eternal purpose but draws His people into communion with Him. Our hope rests not in our worthiness, but in the faithful God who saves through the one true Mediator, Jesus Christ.
