If you trusted in Jesus Christ paying for your sins alone for your salvation, not of your works, you’re going to heaven. No matter what sin you commit in the future, you are going to get raptured up to heaven.
Some people are worried about their salvation because they see verses that show that if they do not produce works or endure until the end, they will not be raptured.
This is because of dispensational raptures. Three famous passages have commonly been misquoted to apply to Christians but are not. They all have conditions to be saved and raptured, i.e. to watch, to pray, etc.
#1. Mark 13
Mark 13:32-37: “But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father. Take ye heed, watch and pray: for ye know not when the time is. For the Son of Man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch. Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning: Lest coming suddenly he find you sleeping. And what I say unto you I say unto all, Watch.”
The above is a passage famously quoted for pre-tribulation rapture (Christians). But it is not. It is for post-tribulation rapture (tribulation saints).
In the above passage, they have to watch as they do not know when their Lord is coming back. Christians, however do not need to produce any works.
#2. Matthew 25
Matthew 25:1-13: “Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom. And five of them were wise, and five were foolish. They that were foolish took their lamps, and took no oil with them. But the wise took oil in their vessels with their lamps. While the bridegroom tarried, they all slumbered and slept. And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him. Then all those virgins arose, and trimmed their lamps. And the foolish said unto the wise, Give us of your oil; for our lamps are gone out. But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves. And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut. Afterward came also the other virgins, saying, Lord, Lord, open to us. But he answered and said, Verily I say unto you, I know you not. Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.”
The parable of the ten virgins in Matthew 25 is also for post-tribulation rapture for tribulation saints. The context is in Matthew 24:3 where Jesus was explaining what the end of the world (tribulation) would be like.
In the above parable, it says that these saints have to watch and not sleep (the same as Mark 13). Jesus was taking them up to heaven for the marriage supper of the Lamb. Once again, this is not for Christians as we do not have to produce works to be saved.
The Christians can tell the signs and an approximate time range of how close the pre-tribulation rapture is. But, the tribulation saints are unable to tell as they are in the middle of the tribulation.
#3. Luke 12
Luke 12:37-40: “Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them. And if he shall come in the second watch, or come in the third watch, and find them so, blessed are those servants. And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through. Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.”
#4. Luke 21
Luke 21:34, 36 “And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.”
Passages for the Christian rapture
1 Thessalonians 5:1-5: “But of the times and the seasons, brethren, ye have no need that I write unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.”
The difference is that Paul says that Christians are supposed to know when is an approximate time and season that the rapture will happen. He also says that Christians are children of light, not of darkness.
1 Thessalonians 4:13-14,17: “But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.”
The only condition to be caught up is to believe in Jesus Christ for salvation in the Christian rapture. There is no need for any works, praying, watching, enduring, etc.
