That's a bad interpretation of Matthew 24 if you think that is talking about being saved by your own works.
24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
The evil servant in Matthew 24 won't be found trusting Christ alone hence what it says here in vs. 50 "he looketh not for him".
But for true believers in Christ, they are kept by the power of God.
1 Peter 1:
3Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, 4to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you, 5 WHO ARE PROTECTED BY THE POWER OF GOD through faith for a salvation ready to be revealed in the last time.
6 For I am confident of this very thing, that He who began a good work in you will perfect it until the day of Christ Jesus.
The good work referred to there, that He began, I believe is faith, not works, because righteousness comes through faith:
9and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith
21But now apart from the Law the righteousness of God has been manifested, being witnessed by the Law and the Prophets, 22even the righteousness of God through faith in Jesus Christ for all those who believe; for there is no distinction; 23for all have sinned and fall short of the glory of God, 24being justified as a gift by His grace through the redemption which is in Christ Jesus; 25whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in the forbearance of God He passed over the sins previously committed; 26for the demonstration, I say, of His righteousness at the present time, so that He would be just and the justifier of the one who has faith in Jesus.
27Where then is boasting? It is excluded. By what kind of law? Of works? No, but by a law of faith. 28For we maintain that a man is justified by faith apart from works of the Law.
19 For I through the law died to the law that I might live to God. 20 I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me. 21 I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain.
12 Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, 2 looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
See that, "looking unto Jesus", the author and finisher of faith, again what the evil servant will not be doing when Jesus comes for "he looketh not for him".
I love this by Charles Spurgeon:
"I sometimes think I might have been in darkness and despair now, had it not been for the goodness of God in sending a snowstorm one Sunday morning, when I was going to a place of worship. When I could go no further, I turned down a court and came to a little Primitive Methodist Chapel. In that chapel there might be a dozen or fifteen people. The minister did not come that morning: snowed up, I suppose. A poor man, a shoemaker, a tailor, or something of that sort, went up into the pulpit to preach. He was obliged to stick to his text, for the simple reason that he had nothing else to say. The text was, 'Look unto Me, and be ye saved, all the ends of the earth.' He did not even pronounce the words rightly, but that did not matter.
"There was, I thought, a glimpse of hope for me in the text. He began thus: 'My dear friends, this is a very simple text indeed. It says, "Look." Now that does not take a deal of effort. It ain't lifting your foot or your finger; it is just "look." Well, a man need not go to college to learn to look. You may be the biggest fool, and yet you can look. A man need not be worth a thousand a year to look. Anyone can look; a child can look. But this is what the text says. Then it says, "Look unto Me." 'Ay,' said he, in broad Essex, 'many of ye are looking to yourselves. No use looking there. You'll never find comfort in yourselves.' Then the good man followed up his text in this way: 'Look unto Me: I am sweating great drops of blood. Look unto Me; I am hanging on the Cross. Look: I am dead and buried. Look unto Me; I rise again. Look unto Me; I ascend; I am sitting at the Father's right hand. O, look to Me! Look to Me!' When he had got about that length, and managed to spin out ten minutes, he was at the length of his tether.
"Then he looked at me under the gallery, and I daresay, with so few present, he knew me to be a stranger. He then said, 'Young man, you look very miserable.' Well, I did; but I had not been accustomed to have remarks made on my personal appearance from the pulpit before. However, it was a good blow struck. He continued: 'And you will always be miserable — miserable in life and miserable in death — if you do not obey my text. But if you obey now, this moment, you will be saved.'
"Then he shouted, as only a Primitive Methodist can, 'Young man, look to Jesus Christ.' There and then the cloud was gone, the darkness had rolled away, and that moment I saw the sun; and I could have risen that moment and sung with the most enthusiastic of them of the Precious Blood of Christ."
