This is a reflective overview of the Five Solas and T.U.L.I.P., written in the belief that these precious doctrines represent what is known as 'Reformed', Bible-believing Christianity. There are things about which sincere, Bible-believing Christians may disagree, but it is this author's view that these doctrines are essential in helping us even begin to fathom something of the unspeakable holiness and sovereignty of God.
