The Holy Spirit intercedes for us when we don't know how to pray? So, if you don't know what to pray for or how to pray... that's okay! The Holy Spirit intervenes for us when we don't know what to say. Romans 8:26 says, "And the Holy Spirit helps us in our weakness. For example, we don't know what God wants us to pray for, but the Holy Spirit prays for us with groanings that cannot be expressed in words."
There is AWESOME power in prayer! James 5:16 says "Confess your sins to each other and pray for each other so that you may be healed. The earnest prayer of a righteous person has GREAT POWER and produces wonderful results!"
Prayer "Call to me and I will answer you.."
Changes "..and tell you great and unsearchable things..."
Things "..you do not know." - Jeremiah 33:3"
