The missionary advantage is God’s clear promise that Jesus Christ will go with us as we make disciples of the “ethnē” (the nations). Jesus will go with us through our Gethsemane. Therefore we can say with the poet, “Riches I heed not nor man’s empty praise; Thou my inheritance, now and always…”
Remind your missionaries one hundred times that Jesus has all authority in heaven and on earth. Remind them that they have a heavenly Father who knows their needs.
