Is preaching still needed today

Is preaching still needed today? With all of these “Say Nothing” preachers in the church today we ask the question, is preaching still needed today? Christians have to be careful of who they allow themselves to be taught by. We have been admonished to know them which labor among us, and are over us in the Lord (1 Thessalonians 5:12). I would also warn the saints of the wolves out there but I still believe in preaching (1 Cor 1:21).
