Put it to the Test
In science, a hypothesis is a falsifiable claim which includes tests that may be observed to fail or succeed. The tests must be logically related to the claim in such a way that, if a test fails, it disproves the claim. A claim that is not testable is not a hypothesis in the context of science and it has no value in helping us better understand our universe.
The more the tests are performed and shown to always succeed, the more reason there is to consider that the hypothesis should be considered fact. However if any of the tests ever fail, then the hypothesis can be said to be proven false.
Are religious claims falsifiable? Most are not but fortunately for this discussion, some are. Here is one that is:
The Lord is near to all who call upon Him, To all who call upon Him in truth. He will fulfill the desire of those who fear Him; He also will hear their cry and save them. Psalms 145:18-19
Since this is a claim about all who call on the Lord, then we can falsify this claim if we find any for whom this doesn't apply. If you're a believer, then you can conduct the test yourself. Pray for help. If you don't get it, it's a failed prayer.
You might say that God will answer the prayer for help, He just hasn't done it yet and there is nothing in the claim about how quickly God has to respond. In that case, let's look at Christians who died because they didn't receive the help they sought. We need an example where help is no longer possible... such as Christians who are praying to be healed from a terminal illness.
Here are some examples. Even though this Pastor attempts to justify the failed tests, he doesn't deny at all that the tests, the cries to God for help, failed. The failed tests disprove the claim put forth in Psalms 145:18-19. Psalms 145:18-19 can be regarded as false.
