No, Matthew 24:48-51 is people saying the Lord is delaying to use it as an excuse not to obey His commands and keep doing what they want, being hateful, staying in a sin, and so forth. Thinking they will have time to repent later, not knowing or caring that their life can be taken at any moment eliminating any chance to repent.
Example: You believe the Lord is delaying His coming so you keep living a life in willful sin, or hatred, disobeying the Lord's commands to walk properly. Then the antichrist shows up tomorrow with his followers and kills you, you lost your one and only change to repent and ask forgiveness of your sins because you disobeyed and delayed being saved because of wanting to do for self and not for Him.
