[They] have pushed what is commonly called "easy-believeism" for decades.
"All you have to do is just believe in Jesus and you can go on and live your life any way you want cause you're good."
That's what [they] espouse. Why? Why do [they] teach/preach that?
Because that's NOT what Jesus said.
He said, "why do you call Me, 'Lord, Lord' but don't do the things that I say?"
He said, "The kingdom of God is at hand, repent and believe the Gospel."
He said, "But unless you repent, you too will all perish.”
If you die today, will you go to Heaven or Hell? Jesus has told us what we must do.
The Day is fast approaching. To quote Q, "Nothing can stop what is coming."
