Acts 4:12

“Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.”

Where it comes from

Peter says this to the religious council after healing a lame man, when they ask by what power he did it.

What it means

The receipt on the card itemizes it: sin, shame, anger, lust, greed, envy, each marked paid, and a grand total of zero. That is what Peter is claiming. There is no other account where those things can be settled, no other name that clears them. It's an exclusive claim, and it's also the most generous one ever made: the bill is covered for anyone who will take it.
