Prayer brings us into UNITY with God. It is not sufficient for us just to pray with our mind but we need to pray in the Spirit, WITH the Holy Spirit of God. When we pray we need to TUNE IN to the Holy Spirit and let the Spirit of God FILL our mind with the mind of Christ so that we will know what to rightfully pray.
The apostle Paul writes in Romans 8:26 that we do not know rightfully what to pray but but the Spirit Himself intercedes for us with groanings too deep for words. When we come into unison with the Spirit of God then the MIND OF CHRIST is instilled/implanted into us. He puts into our mind those things that are important for the Spirit of God and we can pray ACCORDING TO THE WILL OF GOD. We can intercede according to the WILL OF THE SPIRIT and we come into unity with God.
Prayer is not just a matter of reciting your grocery list to God:”Forgive me this and forgive me that, and give me this and give me that.” NO, it is COMING INTO CLOSE RELATIONSHIP with Jesus Christ through His Spirit. We have to SPEND TIME WITH THE LORD and let His Spirit permeate us and FILL us with the MIND OF CHRIST then we will be able to pray according to the will of God and we will also KNOW the MIND of Christ.
May Jesus bless you.
