Paul preached to multitudes but he also knew the value of investing his life in a few key men who would be able to teach others also. Timothy was one of these men as was Titus and even John Mark, who had once refused for discipleship training (Acts 15:36-40).
Si Pablo ay nangaral sa maraming tao ngunit alam niya ang kahalagahan ng pagbibigay ng kanyang buhay sa kakaunting susing mga tao na maaring magturo sa iba. Si Timoteo ang isa sa mga taong ito at si Tito at kahit si Juan Marcos, na minsan na tumanggi para sa pagsasanay ng pagdi-disipolo (Mga gawa 15:36-40).
