If you want examples today of what Jesus warned against in Matthew 7:21-23?
Look no further than Kenneth Copeland and Kenneth Hagin.
That's only a few of many.
Jesus said that there will be MANY in that day!
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but
the one who does the will of my Father who is in heaven. On that day many will
say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in
your name, and do many mighty works in your name?’ And then will I declare to
them, ‘I never knew you; depart from me, you workers of lawlessness.’
They are everywhere to be found.
