I suppose that I should have said what I meant, clearly, in my above post. But I didn't.
The ability for everyone to do miracles is only available for all people, because Jesus took onto Himself and paid for the sins of the whole world when He died on the cross. When He arose from the grave, He showed that He had the strength to do this, thereby conquering the devil who was the author of sin and everything evil.
My point is this. If a person will not accept Jesus salvation, they will lose their life in Hell, even though they do a million miracles in this life.
Yoga? If Yoga doesn't teach about Jesus salvation directly, then Yoga is only a good (possibly) training for the hundred years we live in this life.
Be saved. Dig the salvation info out from the only place that has it, the Bible.
He didnt choose to die on the cross for our sins and if the Romans had chosen to leave him alone or alive for that matter then Christianity would be relatively different but most likely not much.
Also when it comes to his strength to conquer the devil..... well, this was not the point I think anyone should be making. Jesus didnt really need strength against the devil and this is proven in Matthew 4:1-10, amongst other places.
You also mention that the devil is the author of sin and everything evil but this is a weird way to perpetuate a person. First, to claim he is responsible for everything evil is a stretch, after all free will would mean absolutely nothing if we were able to put every amount of blame on one entity instead of being responsible for ourselves. This would also make judgments moot if every amount of evil was just passed by and labeled as the result of the devil.
With all of that said and based on your first statement it wouldn't matter if anyone accepted the salvation of Jesus because everyone would A-Ok and allowed in as the evils was not from their hand alone but rather the result of some evil entity, the same evil entity responsible for everything evil.
Lastly, it seems you are taking the fear of god approach which would mean that we only pray for selfish means to appease a God rather than doing because we feel it is right. God never intended hell as a place for humans to go and in fact would never wish the evil on anyone because he himself would be considered evil. Man is responsible for sending himself to hell. Man must choose that path.
