In considering world religion, noting the vast variety of beliefs and observing the profound differences between them, we can be confident that either  there is no God, so it’s all made up, or  very few people have it right, knowing God as He ought to be known.
Yet God assures us that those who seek Him diligently will find Him. (He 11:6) If we cry after knowledge, seeking it like treasure, we’ll understand what it means to fear Him, and come to know Him. (Pr 2:3-5)
In other words, knowing the God of the universe must be supremely important to us, the most important thing in our lives (Php 3:8), or we may miss Him entirely, living apart from Him, alienated from Him in our ignorance. (Ep 4:17-18) God isn’t one to be trifled with; this is an all-or-nothing space. If He isn’t everything to us, we don’t yet know Him.
