Acts 4:29-31 “And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word, By stretching forth thine and to heal: and that signs and wonders may be done by the name of thy holy child Jesus. And when they had prayed, the place was shaken where they had assembled together: and they were all filled with the Holy Ghost, and they spake the word of God with boldness.” The right for the Church, the Body of Christ, to be used by Jesus, the Head, to carry out God's plans and purposes in the earth was conferred on us by the Blood of Jesus, through the New Birth. Our responsibility is, as hands and feet in the Body, to carry the Good News of the Gospel to the ends of the earth, expecting the preaching of the Word to be confirmed with signs following.
Just as your body is helpless without your head, so the Church, the Body of Christ, is helpless without our Head, Jesus Christ. Through Him God supplies every resource needed for the Body to carry out the will of God, by the Holy Spirit's direction. Without (apart) from Jesus, we can do nothing (John 15:5).
At the same time, your head is helpless without your body. Guillotines proved that. In the same manner Jesus, our Head, can do nothing apart from His Body, the Church. The Head is in Heaven, the Body on Earth; therefore God's Will, Plans, and Purposes for mankind must be carried out through Christ's Body, the Church. It is the Church's responsibility, therefore, to cooperate with its Head, Jesus Christ, by renewing our minds to who we are, what we have, and what we can do in the earth, in and through Christ, our Head. In doing so we'll use our authority, as believers, to further the Kingdom of God.
You have a part in carrying out Jesus's Great Commission (Matthew 28:18-20).
