Rachael Ballman recently wrote an essay for Global Encounters website. here is just a small part of it. Read it in its entirety here.
Missions is the very heart of God! It is the central theme of the Bible and gives Christian people purpose and meaning. Jesus sent out the first missionaries uttering the Gospel imperative, “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you…”(Matthew 28:19‐20a). Missions, then, is fulfilling the command of Jesus to make disciples of ALL nations!
