Or maybe you don't. Pitting one scripture against another doesn't solve your problem. I can turn that statement around to you. Matt. 10:22; 24:13; Mark 13:13 proves that you don't understand what you are talking about. So where do we go from here? I have three scriptures against your one. So I win by three to one.
Matthew 10:21-22, when taken together, as they are a full sentence, kind of destroys your argument. "21 `And brother shall deliver up brother to death, and father child, and children shall rise up against parents, and shall put them to death, 22 and ye shall be hated by all because of my name, but he who hath endured to the end, he shall be saved."
This is talking about the end times. This is not talking about salvation specifically, but about those who in the end times are persecuted, and tormented, and those who are truly God's will endure to the end and be saved. Jude 24-25 is kind of a praise to context like this. God will keep you, just endure through all that is coming. Read the letter to the church at Smyrna.
Matthew 24:11-14 "11 `And many false prophets shall arise, and shall lead many astray;12 and because of the abounding of the lawlessness, the love of the many shall become cold;13 but he who did endure to the end, he shall be saved; 14 and this good news of the reign shall be proclaimed in all the world, for a testimony to all the nations; and then shall the end arrive.
Funny how so far none of your verses do anything to Jude 24-25, and in fact becomes stronger because of Jude 24-25. This is once again, dealing with the end times. (You did know that, right? Or do you just cut up the Bible verse by verse, and pull one out of a hat. Two down, one more to go. You are hanging on one verse, and given what that verse is, it appears to be the same conundrum. It has absolutely nothing to do with your argument. You failed to turn the argument against me, because you don't know the gospel, and you don't know scripture.
Mark 13:12-13 "12 `And brother shall deliver up brother to death, and father child, and children shall rise up against parents, and shall put them to death, 13 and ye shall be hated by all because of my name, but he who hath endured to the end -- he shall be saved."
Oh wow, the same as the first verse, so I actually got two for the price of one.
You really need to learn the various contexts in the scripture. This is, once again, dealing with the end times. The remnant of believers that remain will be purified by persecution and torment, and those who endure to the end, they are the true believers, and they will be saved. Why? Jude 24-25.
