Thank you all for your suggestions.
My current commentary collection on the gospels consist of Ellicott, Godet, F.F. Bruce, D.A. Carson, Hendricksen, Wiersbe, and others.
I do not use Scofield because he is too dispensational for me, as I am more Reformed and Covenental.
Matthew Henry is very general, but is great for a starter commentary.
Black Sheep, I utilize a number of exegetical techniques to gather the meaning of Scripture. Not being knowledgable of Greek, however, is where I rely on commentaries. For example, when I was studying The Acts of the Apostles I discovered that in the Greek of Acts 1:7 the Greek word translated into English "not" was pulled from its standard grammatical place in order to emphasize the fact that the Apostles were NOT to know the explicit details of the end times. It was also through a commentary on 2 Peter 3:9 that I discovered the principle of elipsis. This was a technique in Greek that writers employed when refering back to a previously mentioned subject. It was this understanding that helped move me from Arminianism to Calvinism. Further, commentaries help keep me on track. I am not so presumptuous to think that I can reinvent the wheel. Rather I prefer to stand on the shoulders of those who have gone before me when it comes to doing bible study.
