The Great Commission contains fighting words. Commission is a military term meaning the granting of certain powers or the authority to carry out a particular task or duty. Jesus, as the Field General, commissioned the Eleven, and in perpetuity the Church, and gave the task under His authority to carry on the Revolution of the Kingdom. The Church subsequently, as documented in the book of Acts, started to fulfill the task of the Kingdom Revolution and in the process compiled the documents of the Revolution through the writings of the Apostles, and those writing with their authority. These documents are the New Testament writings, of which contain the words of Jesus, including Matthew 28:18-20.
And Jesus came and spoke to them, saying, “All authority has been given Me in heaven and on earth. Go therefore and make disciples of all the nations. Baptizing them in the name of the Father and the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age.” Amen. (Matthew 28:18-20, NKJV)
The Great Commission was, and is still, an imperative for the Church to carry out. Imperatives are commands given by a person in authority meant to be followed. There is no second guessing or changing the orders of a commanding officer. Christ is the Commanding Officer and His commands always are to fulfill His battle plan for the Revolution of the Kingdom. As is His nature, the commands given are out of the Father’s love (by which His authority is granted Matthew 28:18; and John 5:19-23, 26-27; 12:49-50; 14:10-11; and 17:1-2; Christ’s authority will be addressed later in more detail) and we as the Church for our benefit should be, need to be obeying the call.
