The following lectures by Bill Mounce are a great way to learn (or review) some basic New Testament Greek.
"That our idea of God correspond as nearly as possible to the true being of God is of immense importance to us. Compared with our actual thoughts about Him, our creedal statements are of little consequence. Our real idea of God may lie buried under the rubbish of conventional religious notions and may require an intelligent and vigorous search before it is finally unearthed and exposed for what it is." --A.W. Tozer
