For we know in part, and we prophesy in part.” 1 Corinthians 13:9 KJV
Nobody knows everything. One of the reasons why we must depend on the Holy Spirit in prayer, is because He is the One that knows the mind of God and He is the One that can reveal it to us.
For what person perceives (knows and understands) what passes through a man’s thoughts except the man’s own spirit within him? Just so no one discerns (comes to know and comprehend) the thoughts of God except the Spirit of God. Now we have not received the spirit [that belongs to] the world, but the [Holy] Spirit Who is from God, [given to us] that we might realize and comprehend and appreciate the gifts [of divine favor and blessing so freely and lavishly] bestowed on us by God.” 1 Corinthians 2:11-12 AMP
That’s why praying in the Spirit will help you know the things of God by the Holy Spirit Who helps to pray.
So too the [Holy] Spirit comes to our aid and bears us up in our weakness; for we do not know what prayer to offer nor how to offer it worthily as we ought, but the Spirit Himself goes to meet our supplication and pleads in our behalf with unspeakable yearnings and groanings too deep for utterance.” Romans 8:26 AMP
Lets pray together:
Heavenly Father, I thank You for Your Word. Let Your will for my life be clear as I depend on the Holy Spirit in prayer in Jesus Christ mighty Name, Amen.
