I listened to a sermon and the pastor said a few people told him in the last time that Jesus is coming back really soon. He said the rapture is only for those which are sincere about God, because they will be given crowns in heaven and given orders by God how to reign during the 1000 years. Those which are christians and which are saved but not really sincere, which he said most of the American christians are, will not be raptured but they will have to go through the tribulation. This totally scares me. I don't want to go through the tribulation, but I don't think I'm sincere. I mean I could be doing much more. Seeking God more, praying more and so on. Can I still become more sincere and also get raptured or is it too late to change and those which want to become sincere only to be part of the rapture are not going to be a part of the rapture?
