Groucho,

Actually, they did quite a bit that wasn't preaching. The majority of what Jesus did was demonstrate the love of God in the powerful miracles that He performed and sent His disciples out to do. The problem is when we go out to do those things in the pursuit of "social justice" and doing them in the power and authority of government instead of the power of the Holy Spirit. "Social justice" is a purely socialist/communist concept designed by Satan to distract us away from the power of God. People turn to concepts like that when they are not seeking the Holy Spirit so the power of God can be seen working through them.
