Growing faith requires a hands-on approach. Jesus spent time mentoring and coaching His disciples. In the same way, discipleship today requires a mentor who models what Christ looks like in words and actions. An effective mentor understands how to spiritually discern the disciples' level of understanding and growth to help them grow closer to Jesus.
Paul demonstrated this truth in 2 Timothy 2:2 when he told believers that "what you have heard from me in the presence of many witnesses entrust to faithful men, who will be able to teach others also."
