Repent...

Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord, (NIV)

So repent (change your mind and purpose); turn around and return [to God], that your sins may be erased (blotted out, wiped clean), that times of refreshing (of recovering from the effects of heat, of [a]reviving with fresh air) may come from the presence of the Lord; (Amplified)

Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord. (KJV)

~ Acts 3:19
