But seek (aim at and strive after) first of all His kingdom and His righteousness (His way of doing and being right), and then all these things taken together will be given you besides.
(Matthew 6:33 Amplified Bible)

The Apostle Paul wrote over half of the New Testament and won countries and multitudes of souls to Jesus by himself through the power of the Spirit of God.  He is one of the greatest inspirations to believers.  How did he get to this place and power in God to be able to hear and be led in such a powerful way?  Paul had a very intimate and powerful prayer life he always was in direct communication with God.  In 1 Corinthians 14:18, Paul states: “I thank God that I speak in [strange] tongues (languages) more than any of you or all of you put together” (Amplified Bible).  When you pray in the Spirit you are releasing the will and heart and power of God into this world.  The more time you spend in extended prayer in the Spirit, the more time you are in the presence of God.  The more time you spend with Him the more you will be like Him.  The gifts of the Spirit with the working of miracles will start to flow through you to glorify the Lord Jesus Christ and God Almighty.  You can be a yielded vessel for God to use.  One person praying in the Spirit can save and touch and heal the lives of countless millions.  Jesus said in Luke 24:49, “Behold, I send the promise of my Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high.”  With out His power you are in your own earthly strength.

You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world
 (1 John 4:4)
I will lift up my eyes to the hills; From whence comes my help?
(Psalms 121:1)
My help comes from the LORD, Who made heaven and earth.
(Psalms 121:2)
