Jesus had a very simple way of doing ministry: Discipleship. He ministered for 3 years and almost all of his time was spent with 12 guys. They shared meals, sat around the fire, fished... but most importantly, Jesus taught them about the Kingdom of God. When he was about to be taken into heaven he told them, "Therefore, go and make disciples of all nations" (Matt. 28:19). Discipleship wasn't just something unique that Jesus did with those 12 guys, it is the medium through which the Kingdom of God was meant to spread through all generations.
