Jesus never said to "pray for the sick". Jesus said to "heal the sick".
Jesus said;
Luke 10:19 (KJV)
19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
Is not all these afflictions the result of the power of the enemy, the demonic realm? Believers have authority over all the power of the demonic realm. Jesus had power over the enemy and what did He do? He cast the demons out, He healed the sick, He cleansed the lepers, He raised the dead.
Jesus said;
John 14:12-14 (KJV)
12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
14 If ye shall ask any thing in my name, I will do it.
The same things that Jesus did, believers can do, and "shall" do. When we "ask" we are not begging, we are demanding that the gifts we have been given shall manifest in the person we are praying for. We are commanding that God's Will be done on earth just as it is in heaven. Believers are here to bring heaven to earth.
Just like when Moses and the people of Israel needed to cross the sea. God did not just cause the water to roll back because it was needed. The water did not roll back until Moses raised his rod over the waters. The water did not come into existence just because the Israelites needed it. Moses had to strike the rock first before the water came out. The healings that Jesus performed did not manifest just because the people needed healing. Jesus had to speak first. Lazarus was not raised from the dead until Jesus spoke.
If we want healing and bondages to manifest in a person, then we need to speak to it and command it to leave that person.
Acts 3:6 is a prime example of what to do.
6 Then Peter said, “Silver and gold I do not have, but what I do have I give you: In the name of Jesus Christ of Nazareth, rise up and walk.”
Read Acts 3:1-10 and learn what Peter did.
In the name of Jesus, I bless you with the life of God.
