I have read your Union and fellowship theory, but am still bothered. When you are in the unchangeable union with God and the Holy spirit is bestowed upon you as he promised, but your fellowship is infrequent (being human) will you still be raptured considering the fact that you are not holy as a result of sin? If yes, people would have the idea that they can sin but would still be raptured. Please explain. I find this disturbing.
As humans, it makes sense to us that only those who’ve demonstrated by their behavior that they deserve such a blessing as the rapture should be allowed to go. But that’s applying human logic to a divine issue. The Bible is very clear in stating that our righteousness is imputed to us by faith (Romans 3:21-24) and because of our faith God sees us as being a new creation (2 Cor. 5:17) perfect forever (Hebrews 10:14) as righteous as He is (2 Cor. 5:21). Making our behavior part of the equation would contradict these statements. Remember we don’t become a new creation because of our behavior, we are a new creation because of our faith.
In actuality, where participation in the rapture is concerned, the opposite is true. Those who call themselves Christian but don’t believe Jesus died for all their sins (either because they don’t think Jesus is who He claims to be, or because they think they’re finishing the work of salvation by their own efforts) are the ones who risk being left behind.
