This sonnet by John Donne portrays God as a three-personed being who is knocking to enter the speaker's heart. The speaker asks God to overwhelm and transform him using force so that he may rise up, stand strong, and be made new. However, the speaker's heart resists admitting God due to its captivation by the enemy of God. The speaker declares his love for God but acknowledges being bound to God's enemy instead. He asks God to divorce and untie him from this binding so that God may imprison and enthrall him instead, as that is the only way he can become truly free and chaste.
