Praise is what it takes to live your life in full joy and peace.
Faith brings prayer and out of prayer comes praise.
We pray, or ask, God and He delivers, but we do not go back again and again in prayer. This shows doubt which is a lack of faith. So the blood of Jesus saves us and then when we know the truth it sets us free. The truth is Jesus. So if Jesus is the truth and it is being set free that brings relief, peace, and joy, then we need Jesus.
