Augustine of Hippo
The Scriptures declare: And your mercy will go before me. The resistant person is led to desire, while the willing are supported only to find their longing unfulfilled. Why do we encourage prayers for our adversaries, even when they choose not to live in a godly manner, unless it is because God instills a yearning within them as well? Similarly, why are we urged to seek in order to receive, if not because our desires are fulfilled by Him who grants us those very longings? Therefore, we intercede for our adversaries, asking that God's mercy precede them, just as it does for us; for ourselves, we seek that His mercy would accompany us.
Your compassion will be with me throughout my earthly existence, meaning throughout the duration of my life, not Yours but mine. I will dwell in the Lord's house for a long time (Psalm 22:6). Thus, Your mercy will not only pursue me here, but I shall remain in the Lord's house for all eternity.
