I do have it on, but I very rarely if ever see ads like that anywhere else. It's just on imglfip. And like I said, as many times as I tell it not to show me that add (which I do usually more than once per day) it won't stop. I did eventually decide to turn off ads on imgflip with my adblocker, unfortunately.
Koine Greek would be great for reading the NT Scriptures; for the OT, a good knowledge of ancient Hebrew pronunciation (spelling is the same as modern Hebrew) would be nice, but not really necessary; the same goes for ancient Aramaic. Latin would also be great because all or nearly all writings of the Early Church Fathers were written in Latin or the aforementioned Koine Greek.
Neither I nor Calvin deny that man has the natural ability to choose God or to reject him, but because of man's radical fallenness he will always reject God, unless the Father who sent Christ draws him "And I will raise him up on the last day. It is written in the Prophets, ‘And they will all be taught by God.’ Everyone who has heard and learned from the Father comes to me."
