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
... What does the Lord your God require of you, but to fear the Lord your God,
to walk in all his ways, to love him, to serve the Lord your God with all your heart
and with all your soul, and to keep the commandments and statutes of the Lord,
which I am commanding you today for your good?
Behold, to the Lord your God belong heaven and the heaven of heavens, the earth
with all that is in it. Yet the Lord set his heart in love on your fathers and chose
their offspring after them, you above all peoples, as you are this day.
