It is not just you. This is a unique time for the saints as the Word is truly being fulfilled right before our eyes.
Mark Chapter 13:5-8
And Jesus answering them began to say, Take heed lest any man deceive you:
6: For many shall come in my name, saying , I am Christ; and shall deceive many. 7: And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet. 8: For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows.
As you stated, it has been simmering for a while. For a while it seems the enemy has taken up residence in the church, and you'll probably have noticed that they have been the most faithful. What they would call in first or second Thessalonians "Busybodies". And the number of them that fill the church can disillusion the leaders if they are not as strong as they need to be.
But what I've noticed since the beginning of the year is God has sent bold, praising, and worshiping Holy Ghost filled vessels to these various churches. They are few in the midst of wolves in sheeps clothing. But I tell you when they come in and bring the Holy Spirit down and speak in tongues that atmosphere changes. This is just my perception/opinion, but I feel it's coming to a head because of this.
It's truly a spiritual war, and it isn't going on outside, it's going on inside. Continue to fast, pray, and fill yourself with the Word. Read all of Mark Chapter 13 for the rest of what Jesus instructs about this time 'The Tribulation'. Be encouraged and remember the battle is not yours, it's the Lords.
