According to Matthew 28:18-20, Jesus came and spoke unto them, saying, all power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
Jesus became our example. He himself preached the gospel and how He taught His disciples.
Apostle Paul, followed Jesus’ example, in his whole life preached the gospel and made disciples.
He wrote the letters to his disciples to teach another disciples:
And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also (2Timothy 2:2).
We believe this great commandment is given to all disciples of Jesus Christ, from generation to generation, up to our generation.
We are not to take Jesus’ command and run off on our own, but according to John 17:20-21 we must join with all churches — brothers and sisters in Christ to do this great work together with Holy Spirit as our leader.
Neither pray I for these alone, but for them also which shall believe on me through their word; That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. (John 17:20-21)
Therefore we are open to cooperate with many local churches from any denomination, such as: Baptists, Methodists, Presbyterians, Pentecostals, Charismatics, Adventists, Lutherans, Salvation Safety, etc. As well as Catholics, as long as the church believes that Jesus Christ is ours God and Savior.
It is a wonderful moment, from time to time, seeing ministers from different denomination joining hand in hand the great commandment.
