That's exactly what the osas church does.
They say, "I am safe because I'm the temple of the Lord, I'm the temple of the Lord".
The body of Christ is definitely safe.
By His power.
I am nothing but dirt without Christ. Worse than dirt, a failed and vile person who doesn't even deserve hope.
He however has made me new, and will not ever cast me out.
He promises this to all who believe.
We can KNOW Him, if HE ALSO abides in us.
Those He started in, He continues in until the day of Christ.
It is all about God and trusting in Him. (which is only possible by His power and His faithfulness)
Never about self, unless that is someone were to try to place part of their salvation on their own shoulders... (which those here who you seem to be indirectly pointing your finger at, would not do)
