I've been thinking about our faith in God. If it's too easy to believe, then we won't appreciate our faith much. Just as in the case of collecting unemployment insurance, if it's made too easy, we are likely to take it easy and not look for a job eagerly (I actually know of someone who use the break to take a vacation). Or if free education is available, the incentive to study hard is usually not there. God has given us the free will and he has revealed just enough to us so that when we choose to believe in him, the faith becomes precious. We get the perfect balance.
