Petra Nott asks:

I am interested in learning Greek for the specific purpose of gaining a better ability to study the Bible. My question is this: If I were to study modern Greek, would that be at all helpful to my purpose? Would it be a logical place to start? I appreciate any opinion you are willing to share.

If you already knew modern Greek, that would be a tremendous advantage in learning the language of the New Testament. All of the dialects or epochs belong to one and the same language, so that knowing the form of one dialect or period is extremely helpful in learning any other dialect.
