"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, throughly furnished unto all good works (2 Tim. 3:16-17)."
Just an aside: According to Merriam-Webster's Dictionary, "throughly" is an "archaic spelling for "thoroughly," which means "something done in a thorough manner." I find it hilarious that my spellcheck is not quite ready to accept the word, and that I have to undo its correction. Equally funny, is that when I Googled "throughly," there were 25,900,000 entries! I certainly hope that large of a response is the result of people all over the globe trying to understand the King James Version of the Bible!
What does God's Word have to say about born again believers use of the time He gives them? The first priority is, as our "spiritual police person" said, is to fulfill the Great Commission (Mt. 28:19-20), but have you ever noticed our Lord didn't limit His instructions to the presentation of the Gospel? According to the text (this is my interpretation), having presented the Gospel (the whole Bible, especially 1 Cor. 15:3-4) which has the power of God to save the lost (Rom. 1:16), those who are saved are to be baptized, and then, they are to be taught everything Jesus taught His disciples!
While I admit that we have no recorded discussion of "the sons of God," or the location of Arks, the Apostle John tells us that if all what Jesus taught and said were written down, the world would not be able to contain the books necessary (Jn. 21:25). And, those of us who know Him, know very well that He discussed the entire Bible with any and all who would willingly listen. A perfect example is found in Luke 24:13-32, where Jesus taught two travelers all that the Old Testament had to say about Him (Lk. 24:27).
Faithful believers preach, baptize, teach, ponder, and study God's Word!
