Praying in tongues is praying in line with the divine will of God.
Romans 8:26-27 says, Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. 27 And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
In life, situations will come up that you don’t know how or what to pray for. If you learn to pray in the Spirit, you can pray the divine will of God for anything that may arise in your life. Whatever power you need is made available through you from the Spirit.
You know, you can’t “mis-pray” when you pray in the Holy Ghost. You can’t miss your target! You can’t miss your answer! You can’t miss your victory!
I’m so glad God has given me the ability to be baptized with the Holy Spirit. Where the Holy Spirit helps my infirmities, gives me the mind of the Spirit, and takes me into the will of God. What more can you need?
