That’s the only way we can measure and we probably should first measure ourselves—the beam, so the scripture says.
I'm tired from teaching a RCIA class (that's like enquirer's class for people interested in the Catholic Church). One of the things I said was, "We can argue from Scripture and with reason; we can try to answer your questions; we can give you refreshments and fellowship and all the rest. But it will come down to you and God. We should all pray for each other."
