Matthew 28:18-20 says, Then Jesus came to them and said, “All authority in heaven and on earth has been given to me.  Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,  and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”

As Christians it is our duty to make disciples of all men, baptizing them in the name of the Father and the Son and of the Holy Spirit.  The Name of the Father, the name of the Son and the name of the Holy Spirit is Jesus.  Baptizing them in the Name of Jesus Christ for the remission of sins. Then receiving the promise of the Holy Ghost with the evidence of speaking in tongues.
