This is a subject very important to the body of Christ. The authority of the body of Christ in the earth. As a born again christian you have a right to use the power and authority of Jesus to do his works while He is seated at the right hand of the Father. We just got through finishing celebrating Resurrection Sunday, Jesus coming and saving us from our sins and providing salvation, but many don't realize what else Jesus did. He restored you to your original God given authority. Because of Adam somethings came into the earth that God never intended and so man fell from the place of authority God intended. The first Adam pulled man down, but the last Adam(Jesus) raised us back up (1Corinthians 15:45 Ephesians 2:6). God raised us up through Jesus. When Jesus walked the earth He took authority over things as a man anointted by God. And as such as the Roman Centurion said "All you have to do is speak" for things to obey him (Matthew 8:8,9). And He passed his authority to his disciples (Matthew 10:1,8). And with that authority they went out and did the works of Jesus (Mark 6:7,13). Jesus passed his authority by his words. And as He authorized them He authorized you. The only question is do you believe (John 14:12 Mark 16:17,18). You have that authority whether you use it or not is up to you (Matthew 17:20). Jesus said "All power(authority) is given unto me in heaven and in earth" then he told them to go in that authority (Matthew 28:18,19). Understand in Ephesians 1:22 it says God has put all things under the feet(authority) of Jesus and since they are under his feet they are under your feet(authority). He is the head and we are the body of Christ (Ephesians 1:23). So what the head wants to do He has to do it through his body the church. So whatever you ask(command) in his name you should expect to be done just as if Jesus was speaking. When you speak in Jesus name you are speaking from your level of authority in Christ not within yourself.
Now when God first made man He gave man dominion over all the earth (Genesis 1:26-28). That's why Jesus had to come as a man. A man got us in this mess (the curse) so a man had to get us out (Galatians 3:13). Because God gave man dominion He authorized man to operate in the earth. That's why have you noticed when Jesus was raised from the dead He didn't heal one person, He didn't cast out one demon, He didn't do one miracles and that's because He was restored to his Divine self. He had his glorified body and God only authorized those with a physical body to have dominion. So whatever Jesus wants to do He has to do through you. That's why Jesus told us to occupy until He come (Luke 19:13). Occupy means-To take possession of and maintain control over by force. Isn't that what God told Adam to do (Genesis 1:26-28). You have a force behind you. Have you ever been in a wind storm and tried to force your way against it, but had you got in the flow of it then it would have pushed you. Look at Job 8:2 God's words are as a strong wind. Get in the flow of God's word and let it push you into your distiny. Jesus can't take possession for you, He backs you, but you have to step out in faith. Jesus backs you, that's why He said Whatever you bind on earth will be bound in heaven and whatsoever you loose on earth will be loosed in heaven (Matthew 18:18). Notice that it starts with you so if there's something going on in your body speak to it, if there's something going on in your family speak to it, if it's something going on in your home speak to it in the Name of Jesus.
Side Note: Be careful what you speak over your body. Look at Genesis 1:26-28 again, notice "Let them have dominion over all the earth". What is your body made of ? Earth (Genesis 2:7). Notice Psalms 8:4-6 God has put all the works of his hands under man's feet. And your body is a work of his hands. Now understand that you are a spirit with a body and it's the spirit man that has authority. And when you have authority all you have to do is speak (Matthew 8:9). So be careful what you speak- I can't remember anything, these old bones can't do what they used to do you are exercising dominion.
I thank God for this revelation and I encourage you to write the scriptures down and study them for yourself.
