I have greatly benefited from access to preachers all over the world. I can listen to lectures at Covenant Seminary or masterful exposition from Zambia. We're not even limited to preachers alive today. Sermons from men like Tozer, Ravenhill, Murrell, and Lloyd-Jones are available to anyone with streaming capabilities. This is a cause for rejoicing.
But a concern also arises. Preachers now face to the temptation to preach to their internet audiences instead of their own congregations. Content is modified in order to accommodate the larger audience. If this happens, you can be assured the people of God will suffer. May God help us to stay sober-minded, and keep our hands to the plow.
