Because the caliber of the messengers determines the effectiveness with which the Message is presented, missionaries need to have the finest kind of training and experience. Even more important, they must have a sterling character and a Spirit-filled life that radiates the power and love of Christ. Such high standards are found in the life of the great missionary, Paul. He was well-educated and brilliant. He was a humble and devoted servant of his Lord and Savior. He was called: "As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work where unto I have called them" (Acts 13:2). This combination of preparation and spiritual qualities was needed in his day. It is also needed in our day, for nothing less can overcome the tremendous obstacles that face the missionary.
