Thanks for the links, but I do not put much trust in NDE testimonials because the NDE descriptions from other faiths testifying its own beliefs, are available, too. Same with the hymns and poetry.
Like I said earlier, seeking evidence is an indication of wavering faith.
It is true that people from other faiths have NEDs, but that still testifies to the supernatural, and even witchcraft does that. Then they issue becomes which one is the right one. Moses 1st 3 miracles were duplicated by the devil (magicians), but he outdid them.
As for seeking evidence being an indication of wavering faith, that is true except sometimes when prayerfully seeking direction, but faith that has no evidence has no reality. The born again church did not grow to be what is (in the positive sense) because of good business strategy, or centralized CC, etc., or provides religious ritual, but most essentially because life giving truth and faith results in evidence.
I think the (sober) “Venture in faith” documentary (download) and many written testimonies are modern examples of what I am talking about, without asserting perfection. But every generation much have living Biblical faith, and share and maintain it.
And despite my faults and failures of faith, i can well testify that God keeps his promises as we trust and obey, and is also faithful to keep His promise to let you know when you are straying from that path.
Forgot the hymns. While I do not know of any comparative research, I really think that the abundance of hymns by evangelicals, while being a minority, are unmatched in amount (per capita) and kind of content. Blind Fanny Crosby wrote 8,000, and others wrote thousands, testifying of what Christ did in their soul and the realities of the Christian faith.
