Who or what's holding back or keeping lawlessness and the lawless one back?
God is keeping it back!
Lawlessness is kept back by God, by design... but there is coming a specific day when it will be released to wreck havoc upon a world kept in the dark to its deception, delusion and demise.
Paul helps us with this in 2 Thessalonians. He says, "For the mystery of lawlessness is already at work; only God, who now keeps it back will do so until the Antichrist arises out of the midst of the sea (out of people, nations). And then the lawless one will be revealed, whom the Lord will consume..." (2 Thessalonians 2:7-8)
Lawlessness has always been a work... but for those it is at work in, usually, have no clue how or why or when it's been at work in them.
Great Sermon! Woke up crying and asking God when the restrainer would be taken away, really unsure of even who the restrainer is, found this sermon, it spoke to my heart, calmed my fears and told me who the restrainer is. It is God this I believe. Your sermon was edifying and much needed. God answers prayers and still speaks to us in manifold ways~! Thank You and God Bless~!
