Hi Moose.
God bless you brother and nice to hear you witnessing to someone.
I've been witnessing to a few of my Hindu friends and I've always come up against a wall too. Here are some of the challenges that come across while witnessing to Hindus.
(Remember that at the end of the day it is God who has to speak to that person and they, who have to respond)
1. Hindus are usually brought up with strict tradition and very religious foundations. It is family and tradition above everything else.
Hindus having such tight bonds are usually unwilling or afraid to consider a different religion for the fear of ostracizing families.
There's also the usual safety of stepping out of something known and comfortable into something else entirely.
Imagine growing up with something that you are safe with and familiar, that you have always believed to be right and to let go of that - that is very hard!
2. Hindus view everything as sacred. It's easier to accept Jesus as "one of " many Gods than to accept a one true God. To move from polytheism to monotheism is another hurdle.
3. Prejudices - They view Christianity as a religion that attacks theirs because it calls out on idolatry and hence they may be inclined to be hostile towards it.
I do know many people who converted to Christianity from Hinduism and most of them came out of sheer desperation.
They were suffering from ill health or extreme problems, and in the end, their desperation led them to pray to God –who answered them.
Beware; if your friend is very knowledgeable, then it may spiral into a debate, which usually is unfruitful.
You have to be sure -very sure that your God is TRUE. Remember Elijah with the prophets of Baal?
Keep praying. Praying at all times and never ceasing.
Put on the armour of God.
God bless you.
