There are things we are not meant, designed to "understand". We re here to reproduce life, protect it and follow God's words to find genuine hapiness. It's a constant challenge, a constant selection. Attempting to go further in terms or reasoning leads to suffering or believing in absurdity which is nihilism and leads to destruction and death. Atheists are the closest of believing in absurdity. They are at war with christians and muslims worldwide, even if most of the time they re "seduced" by islam after abandoning christianism.
