You have a dilemma that is even greater than the one you think you have of not knowing which is the right God. It's the dilemma of 'guilt'. Everyone … - Ray Comfort

Amazingly, the religion of Buddhism denies that God even exists. It teaches that life and death are sort of an illusion. That’s like standing at the door of the plane and saying, “I’m not really here, and there’s no such thing as the law of gravity, and no ground that I’m going to hit.” That may temporarily help you deal with your fears, but it doesn’t square with reality. And it doesn’t deal with your real problem of having sinned against God and the reality of hell.

Interestingly, Islam acknowledges the reality of sin and hell, and the justice of God, but the hope it offers is that sinners can escape God’s justice if they do religious works. God will see these, and because of them, hopefully he will show mercy—but they won’t know for sure. Each person’s works will be weighed on the Day of Judgment and it will then be decided who is saved and who is not—based on whether they followed Islam, were sincere in repentance, and performed enough righteous deeds to outweigh their bad ones. So Islam believes you can earn God’s mercy by your own efforts. That’s like jumping out of the plane and believing that flapping your arms is going to counter the law of gravity and save you from a 10,000-foot drop. And there’s something else to consider. The Law of God shows us that the best of us is nothing but a wicked criminal, standing guilty and condemned before the throne of a perfect and holy Judge. When that is understood, then our “righteous deeds” are actually seen as an attempt to bribe the Judge of the Universe. The Bible says that because of our guilt, anything we offer God for our justification (our acquittal from His courtroom) is an abomination to Him, and only adds to our crimes. Islam, like the other religions, doesn’t solve your problem of having sinned against God and the reality of hell.

There is absolutely no point in being healed in our bodies, then dying in our sins and spending an eternity in hell. It would be better to die of cancer and go to heaven because of that cancer, than to live in perfect health and end up in hell.
