The Tribulation is a time in history when the sin that is in mankind will no longer be shut up inside their heart, but brought to the surface; like a magnet draws mettle. (spelling intended).
Matthew 24:21 For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will.
A few years ago, I had a vision of a VERY LARGE MAGNETIC HAND, touching down upon the earth. It slowly started lifting and as it did, there were some people who were attracted to this magnetic hand and were lifted up with it. Those who were not, were left on the earth where chaos and confusion intensified. (What I saw was mettle shavings moving about like crazy ants move quickly and without direction).
As we who are held in the palms of His hands by His grace are raised up with Him as He lifts His hand, those who remain are feeling the effects of the removal of His grace upon them and this removal exposes darkness upon the earth and in hearts – this purpose is to show that it is only by God’s grace we can live in a peaceful existence.
The hand of God is lifting but the peace of God is with all those who are firmly in the palm of His hand.
