Literally, a “MISSION” is just a job. When we became a follower of Christ we should have become a “missionary.” This harmonizes with the command of our Savior, “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.” Matthew 28:19,20.
With this in mind every real Christian is a missionary. Too often we stop Christian growth at baptism. And we remain at that point until death without realizing or accepting any further responsibilities.
The church stagnates if we stop at this point. In a way, the Bible is a manual on how to be a Christian. We must recognize our duties that are spelled out in other scriptures if the church is to grow and others are to be saved—and also even if we are to be saved—the great Apostle, Paul, said, “Therefore, my beloved brethren, be ye steadfast, unmovable, always abounding in the work of the Lord, forasmuch as ye know that your labor is not in vain in the Lord.” I Corinthians 15:58
Our love for God, our love for the souls of others, and even our love for our own soul demands that we do all we can to teach others the saving Word. If we do this, we are missionaries.
The words of Christ in Revelation 2:10 should be in our mind constantly: “Be thou faithful unto death, and I will give thee a crown of life.”
