Well, I went to synagogue and Catholic church and Evangelical churches as a very young person when searching for Him in my life. Our neighborhood didn’t have much in terms of access to the Word of God. The “missionaries” weren’t all that fearless, it would seem.
Jesus is like nothing else. If you only knew congregations that had built religions around Him, your approach is understandable.
But for those who personally encountered Him upon being willing to yield without manmade pontificating — He is a veritable fountain of grace.
How did songs like Amazing Grace come to be written? You might research into that. Just for an example. There is no Catholic or Jewish equivalent.
