Yes, I agree that even one verse can have more than one doctrinal point to it. HOWEVER, Mark 24 AND 25 are all part of the Olivet discourse in that following expound on the premise.
To say that some refused the call is to say that God is not omnipotent. The bible says NONE resist his will.
Romans 9:19 You will say to me then, “Why does He still find fault? For who has resisted His will?”
20 On the contrary, who are you, you
foolish person, who answers back to God? The thing molded will not say to the molder, “Why did you make me like this,” will it?
If you are trying to prove that man has a will free from God's will, that is a dogma put forth by the Roman Catholic religion to enforce their decree to repent or perish during the Inquisition. The 2ndCouncil of Orange in 529 agreed on those doctrines that would look a lot like calvinism. That is because 'calvinsims' are the doctrines of the bible.

The canons of the Second Council influenced the interpretation of Augustine in the later medieval Western Church, such as by Thomas Aquinas. Classical Protestantism affirms the theology of the Second Council of Orange and has appealed to its conclusions to make a case that the Lutheran and Calvinist doctrines of sola gratia, sola fide, solus Christus, and original sin as total depravity had already been taught much earlier than the 16th-century Protestant Reformation.
