Kingdom now theology is in churches today.
Romans 5:17 Weymouth’s Translation For if by the trespasses of the one, death reigned as king through the one, much more shall they who receive the abundance of grace and of the gift of righteousness reign as kings in the realm of life
I believe that it is a dangerous theology that is designed to lead the churches into becoming united with mystery Babylon.
Why is that?
Well many reasons. I have seen it personally. The charismatics and pentacostals believe in it, some of them.
Acts 15:16 KJV  After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:
Basically they say like this:
- “We are going to build Gods kingdom on earth. Not the antichrists kingdom, Gods kingdom.”
But what they really are building is Babylon.
I believe the people who do this are generally unsaved.
John 14:12 KJV  Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
And then they talk about that they are going to do greater works than Jesus. I guess they say that because of that they don’t understand the work that Jesus did on the cross. It is foolishness to them. They want respect in this world and to rule over others, especially rule over born again believers.
(I Corinthians 1:18 [KJV]) For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
They might say that the gospel is in Acts 2:38.
(Acts 2:38 [KJV]) Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
They might say that if you don't speak gibberish (their interpretation of speaking in tongues) then you have not been given the Holy Ghost.
But we dont stop them from doing whatever they want to do.
(Luke 9:49-50 [KJV])  And John answered and said, Master, we saw one casting out devils in thy name; and we forbad him, because he followeth not with us.  And Jesus said unto him, Forbid him not: for he that is not against us is for us.
We just depart from them and let them be accursed!
(Galatians 1:8-9 [KJV])  But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.  As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
