People will rarely go on to see the value of math beyond a high school level. In class we memorize the multiplication tables, use formula sheets, and learn techniques such as algebra and calculus all for the sake of solving hypothetical math problems that are hardly practical in every day life. When are normal human beings going to need to use logarithms? Probably never. But just because math is not practical to the every day man does not mean that math is not practical at all. Engineers used calculus to put man on the moon, artists use the golden ratio in designs, and economists use statistics to create models and make predictions. Math is real and it produces real results.
God may not seem real to us when we are spiritually uneducated. If all we know about religion is a couple bible verses and stories of Noah's ark, then God will be as real as someone buying 60 watermelons in a math problem. Not very real at all. But God, unlike math is a lot more practical because of the one practical reality we all face, death. We may not all build rockets as engineers but we will all eventually die and for that reason we all need to be Christians because there is a life after death and the only way we are going to experience it is through God. This sentiment of an afterlife may be hard to believe or seem unreal, but once we become expert engineers of Christianity, God will become more tangible to us.
