I feel exactly the same way that you do! I talk to my family and friends also sending them emails about the things that are about to happen. Like you I am on the ROOF TOP SHOUTING !!!!! JESUS, KING OF KINGS AND LORD OF LORDS, IS COMMING!!!!! WAKE UP BEFORE IT IS TO LATE!! Nothing........they don't seem to even care. They think I am crazy just like you said.
I also have lost interest in everything. About a year ago the world seemed bright and shiny to me and Jesus seemed dim. That has all changed. Now Jesus is bright and shiny to me and the world is dim. I no longer have the earthly desires that I once had.
I also feel the same way as you about worshipping. I also weep for family, friends, and the world of lost people. I feel brokeness before the Lord. In church during our praise and worship time I can just cry and cry. One Sunday I couldn't stop. I also just keep thanking and thanking Jesus for what he has done for me. It is making me focus on allowing the Holy Spirit to convict me. He is preparing us to be his bride without spot or blemish.
I am also exited beyond all words like you!!!! I guess this is how the Lord is bringing out his "TRUE" bride. It is so hard to just "wait" for Jesus. We all want him to come NOW!!
So, you are not the only one feeling this way. I am sure there are many, many, more that feel the same way. That was a beautiful song about grace. Thank you.
God bless you
