Something I've considered is that a relativistic world is a world without answers. Consider pic related; even as satire it has it's merits. If it's still argued that much of our existence is still subjective and affected by the flux of events and time, then the best way for us to see the world 'subjectively' would be in compartmentalizing or removing oneself from the grander experience and trying to find something 'outside' the world, either through the internal (prayer, meditation, contemplative study) or the external (mystical experiences, psychedelic intoxicants, etc.) This is where God can be conceived as a being 'outside' the universe; He cannot be affected by causality or even existence in the universe, he's the Creator that works from the outside, and from this we can imply that He has a certifiably stronger objective base than any mere man.
And yet God is unique in that he still respects our free will. For all intents and purposes he is incomprehensibly all-powerful and all-willing, and yet He would rather you fall and try again than to probe into your mind and force you to do something against your agency. His love is unconditional and far beyond the scope of any human emotion, and yet we receive it despite our shortcomings as flawed beings.
As to proving the spiritual world, that is something they must do themselves. They have the arrogance to assume that the material universe is our only universe, and that there can be no other alternative to this. Nihilism grips them like a cancer, enslaving them to temptations of all shapes. Consider for a moment what kind of being would want people to believe that there is nothing; how much control could you exercise over them, how much influence could you impart on them? It is no surprise then that those who worship the material world often fall into Satan's hands.
The answers are not found here, they are found in God.
