I know that that there seems to be alot of confusion about when the rapture will happen (ie, pre, mid and post). Could it be possible that there is two or three different ones? Pre-trib rapture or first fruits rapture, bride of Christ. Mid-trib rapture also main harvest rapture?
What about Salvation,(spirit salvation) once saved always saved? If so why are we told by Paul to work out our own salvation with fear and trembling, could this be a soul salvation, one based upon works? The answers to these questions are yes, the Bible is not contradicting.  The web site below answers these questions  i encourage you read and with the guidance of Our Lord and Savior to provide these answers to you. Personally the study on The Five Crowns brought me to these conclusions.
