“‘THEREFORE MY HEART REJOICED AND MY TONGUE EXULTED EXCEEDINGLY; MOREOVER MY FLESH ALSO WILL LIVE IN HOPE [that is, will encamp in anticipation of the resurrection];”ACTS 2:26 AMP
This is a quote from David, he had a true revelation of the cross back then and knew one day that he would be redeemed. David says the joy of the Lord is our strength. Think positive.
Sing to Him, praise Him. It brings down strong holds. Your mouth is a powerful tool. The enemy wants you to be sad and quiet. Do the opposite! Declare! REJOICE! Live in hope. All is well!
