Matthew 24: 22 And if those days had not been cut short, ‘Look, here is the Christ!’ or ‘There he is!’ do not believe it. 24 For false christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect. 25 See, I have told you beforehand.
Just an observation: thankfully the phrase “if possible” there in Matthew 24:24, shouts loudly to us that it is indeed not in any way possible for the elect to be deceived. God will make sure His chosen ones are safeguarded from the deception, though all around them fall for the lies.
The more time goes by, the more I see that the ONLY reason you or I are ever kept from such deception is not because of any smarts on our part, but God’s Sovereign choice and mercy.
