God Takes Away Truth from "True Believers" in Time of Judgment
Significantly, God's warning about taking away that which one has, is given in the context of Jesus explaining that He speaks in parables:
Matthew 13:11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
But it is not until the Lord comes in Judgment Day that this "taking away" is carried out:
Matthew 25:19 After a long time the lord of those servants cometh, and reckoneth with them.
And,
Matthew 25:28 Take therefore the talent from him, and give it unto him which hath ten talents.
29 For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
What are we to make of this?
We know that God opened the Scriptures at the time of the end to reveal much hidden truth. The hidden information was kept hidden by God because He sealed it up in His Word in the form of parables (mysteries). At the time of the end (great tribulation especially), He gave His elect people understanding of these parables thus spiritually "giving to them" talents or pounds.
Numbers of professed "true believers," though, who once said they understood and agreed with these spiritual truths, later turned back from them after the date of May 21, 2011 did not happen as they had expected. But this was the time wherein the Lord of the servants came to reckon with them. And in finding them unprofitable servants, He began to take away truth from them. And since the judgment is a prolonged period of time (according to Biblical evidence we expect it to be 22 actual / 23 inclusive years), they will turn more and more from truth as time goes on.
