Joel 2:12-14

Therefore also now, says the Lord, turn and keep on coming to Me with all your heart, with fasting, with weeping, and with mourning [until every hindrance is removed and the broken fellowship is restored]. Rend your hearts and not your garments and return to the Lord, your God, for He is gracious and merciful, slow to anger, and abounding in loving-kindness; and He revokes His sentence of evil [when His conditions are met]. Who knows but what He will turn, revoke your sentence [of evil], and leave a blessing behind Him [giving you the means with which to serve Him], even a cereal or meal offering and a drink offering for the Lord, your God?
