Zephaniah 3:17 (Amplified Bible)
17The Lord your God is in the midst of you, a Mighty One, a Savior [Who saves]! He will rejoice over you with joy; He will rest [in silent satisfaction] and in His love He will be silent and make no mention [of past sins, or even recall them]; He will exult over you with singing.
What an awesome thought to think of the Lord rejoicing over us and doing it with joy as His Word says! Knowing that He has forgiven and forgotten our sins, if we've confessed and repented of them, also provides great comfort. I can't even imagine the next part of the verse...He will exult over you with singing. Webster's defines the word exult as being exceedingly joyful, or to leap with joy. So not only does the Lord rejoice over us, He does it exuberantly and with great joy. Isn't that wonderful? See how great the Father's love is for us!
