Even now, says the Lord, “Turn and come to Me with all your heart [in genuine repentance], with fasting and weeping and mourning [until every barrier is removed and the broken fellowship is restored]. Rip your heart to pieces [in sorrow and contrition] and not your garments.” Now return [in repentance] to the Lord your God, for He is gracious and compassionate, slow to anger, abounding in lovingkindness [faithful to His covenant with His people]; and He relents [His sentence of] evil [when His people genuinely repent].

Joel 2:12-13 (AMP)
