While the source of your prayer power is the Holy Spirit, the instrument of your prayer power is you; it is you when you are filled with the Spirit and pray in the Spirit and in Jesus Name.  In fact, it was by your prayer in Jesus name that the Holy Spirit was given to you, and by your prayer in His name the Holy Spirit filled you and empowered you (Lu. 11:13).

Notice what I am saying.  You are the instrument of power; but the power comes through your prayers only when you depend on the Spirit and pray in the Spirit.  Accordingly, when we pray in the Spirit we are saying to God, “I can do nothing without you Lord; You are my strength; I wait on You for power to do whatever it is You want me to do.”  And then, out of our weakness,  He gives us the omnipotent power of Christ (2 Cor. 12:9).

Jesus said, “If you abide in Me, and My words abide in you, ask whatever you wish, and it shall be done for you” (Jn. 15:7).  What power!  To be able to receive whatever we wish!  And it comes to us when we give ourselves totally to Him as His instrument of righteousness. Romans 6:13 says,

And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God.
