“Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father.”
Jesus said it was not Him but the Father in Him that did the works He did. In Acts 10:38 we are told that God anointed Jesus with the Holy Ghost and power who went about doing good and healing all who were oppressed of the devil. Jesus did not do the miracles He did because He was God, if that were true then we would not be able to do the works He did for we are not God. Jesus most certainly is God who came in the flesh to the earth, but He did the works by the anointing of the Holy Spirit.
Upon putting our faith in Jesus Christ we can do the same works Jesus did, because it is the same Holy Spirit living in us that was with Him. He has given us a Helper to do the work. Now all we have to do is have faith in Jesus, faith in what He has said to us, and have faith in what we have seen Him do by the Holy Spirit within Him, and we too can do the same works.
He is the Head, we are the body. We are His hands and feet, and His Word spoken in this earth. Step out in faith and know that you have the same Holy Spirit in your life to do the work. As Jesus said in Matthew 10:8, freely we have received, freely give. It is through the name of Jesus, faith in His name that you can set the captives free.
