I’m often asked how many disciples one person can mentor. I believe you can mentor people at various levels. Jesus called 12 men to follow Him closely, and He discipled a group of women (Luke 8:1-3). He also trained a group of 70 in ministry (Luke 10:1), and He preached to crowds. But Jesus invested more time in three followers (Peter, James and John) and John seemed to have the deepest revelation of the Savior because He had such close access to Him.
Jesus did not invest the same amount of time in everyone. He influenced people on different levels, but He focused on the few. Don’t spread yourself too thin. There is no set number of disciples you can mentor. But regardless of how many people you influence, make sure you invest your most quality time in the “Johns” whom God has put closest to you.
