It's not up to you to say if you are keeping the word of God, but to do the best you can do according to the Scriptures. Though some are given a "white stone" (Rev. 2.17) or some special sign they are an overcomer. Watch and pray encompasses much more. The Bible says to run the race. So run. Don't concern yourself with introversion, but keep your eye on Christ at all times. Trying to keep the 5 pillars of Islam for initial salvation by works or to be kept saved is quite unlike God's approach. The Bible teaches a person can never lose salvation so when the Bible says to keep the conduct of Matthew 5-7, for example, don't accuse God of being Islamic. The first rapture is according to readiness. If you have the pretention of assuming you will be raptured beforehand then you are seen as not ready already, because that is not a humble position to take. What I do is I run the race and leave it up to God if I am ready to be raptured alive at the first rapture. If I am not, I will know there were some things to overcome. One of the greatest sayings I ever heard was from T. Austin Sparks who said, referring to the partial rapture, "there are advanced parties and harbingers in every sphere." Firstfruits and later harvests (1 Cor. 15.23). So it is with the first rapture. Even Paul did not count himself as worthy for the first rapture. Christians are often comparing themselves with non-believers or wheat with tares, when the Bible emphasizes more often than not comparing wheat with wheat.
