The most important ministry I recommend is:
The Local Church
Obviously, there are many more ministries I could mention. But the most important ministry is the one through your local church (seeing as how the church is the pillar and buttress of truth in the world). Our local church, even though we are living overseas, is Kirby Woods Baptist Church in Memphis, TN.
With that being said, here is a short (and growing as I am exposed to other sound ministries) list of what I feel are solid, biblical evangelical ministries to edify the saints.
Preaching
John Piper, Bethlehem Baptist Church
John MacArthur, Grace Community Church
Paul Washer, Heart Cry Missionary Society (mostly Paul’s preaching ministry, as I am not too familiar with their missions work)
Jeff Noblit, Grace Life Church of the Shoals
Mark Dever, Capital Hill Baptist Church
Apologetics
James White, Alpha and Omega Ministries
Evangelism
Ray Comfort & Kurt Cameron, Way of the Master Ministries
Todd Friel, Way of the Master Radio
Noel Wright, Sunday School Ministry
Family and Social Issues
Dr. James Dobson, Focus on the Family
Dave Ramsey, Financial (not really a ministry, but built on biblical principles)
