'Shall' in the Bible

Dear friends, we are now God's children, but what we are to be in the future has not yet been fully revealed. We know that if Christ reappears we shall be like Him, because we shall see Him as He is.

And in this way we shall come to know that we are loyal to the truth, and shall satisfy our consciences in His presence

If any one sees a brother man committing a sin which is not unto death, he shall ask and God shall give him life--for those who do not sin unto death. There is such a thing as sin unto death; for that I do not bid him make request.
