Quoting bits of the Bible out of context is dry stuff. When you factor in personal interpretation, of a translation of a translation, you can get lost quite easily.
That’s why Catholics have a backup in our Tradition and in the occasional saint the Church throws up. Add in the Sacraments and Indulgences, icons and statues and devotions, priests and nuns and bishops and you have to be very wilful to avoid going to Heaven, with all that help available to push you up the mountain.
And what help is a book, if a man can’t read. Or he says to you, as a previous poster has said “Prove what you’ve said is the word of God”.
Early Christian saints, and later Catholic ones, did miracles. Can’t beat that for bringing in lost souls.
By comparison, Protestantism and Islam are spiritual deserts. It’s as if they’ve both decided to throw away the oars of their boats, expecting the current to bring them into shore.
