A Call to Repentance - Part 1

(the LORD speaking to His people directly and through Joel)
    "Yet even now," declares the LORD,
"return to me with all your heart,
with fasting, with weeping, and with mourning;
    and rend your hearts and not your garments."
Return to the LORD your God,
for he is gracious and merciful,
slow to anger, and abounding in steadfast love;
and he relents over disaster.

Joel 2:12-13 (ESV)
