I suppose I am not surprised, or at least shouldn’t be.
Gospel can penetrate into a Hindu society. A people that deems it okay to be spiritual (rather than the stiffer upper lip of much of Western society) can be approached with the gospel story. There is interference from the devil, of course. And I believe such a thing blew up in my face when I evangelized a Hindu without enough prayer to support it. The church where I was going was like, well that’s nice. It should have been like “hey brother! you’ve got a live one on the line now. we will make this a #1 prayer priority.” I ended up with health and job problems and briefly went homeless. So I know how hell can kick back. I’m not telling Christians to be stupid and go off half-cocked. I’m telling them to be wise, to use prayer leverage. Then by all means, act.
They often opt for bad yokes which turn out neither to be light nor easy. And yet lust keeps them there, in that hard, difficult yoke.
If every church took on this problem with prayer as you said, we could have a wonderful impact. Our culture has lost knowledge of God's forgiveness and just how light the yoke is! All those young people would be stunned to know how fair God is.
