When we present reasonable evidence for a spiritual concept to someone who believes differently, why is it so rare for people to grow and change?
When our assumptions or reasonings are flawed, people should point this out with a carefully reasoned position, especially when we invite them to do so and listen intently to their concerns. So when people persistently reveal shallow, inconsistent, irrational reasons for unbelief this can be frustrating, until we consider the inherent nature of the carnal mind. (Ro 8:7)
Take for example the overwhelming historical evidence for the Resurrection of Christ. The proof is straightforward and unanswerably sound, yet it’s generally unconvincing to those who aren’t raised in church. It’s hard to fathom a more reliable testimony than the apostles have passed on to us. What does it take to convince people?
One might think miracles would help, but this is untrue historically: miracles never have convinced the masses. (Jn 12:37-38)) Neither has earnest, rational debate. (Ac 6:10-11) There isn’t much left.
Evidently, our values determine what we notice, what we’re receptive to, and what we find credible. A temporal value system disvalues eternal things and obscures them, so Christ tells us to align our value system with God’s so we’ll be able to rightly value and perceive spiritual truth. (Mt 6:19-21) This is where we must begin: it’s the fear of God. (Pr 1:7)
When our eyes focus properly we’re able to see clearly (Mt 6:22), but when improper focus impairs our vision the light we’re seeing might as well be darkness. And if we’re mistaking darkness for light, thinking we can still see, we’re worse off than if we knew we were blind. (23)
Further, when we don’t love truth we open ourselves up to deception (2Th 2:10), inviting supernatural wickedness to further restrict our vision and perception. (2Co 4:4) No one imprisoned like this can overcome and believe on their own. (Jn 12:40)
Lack of love for the truth equates to love of the lie, which leads to making and receiving lies, which ultimately damns the soul. (Re 22:15) This disposition is evidenced in part by preferring Man’s praise to God’s, rendering us unable to perceive and receive the reality of His Son. (Jn 5:44)
Evidently, God must give us a love for truth and open our eyes in order for us to believe in and follow Him. (Jn 1:12-13) Without Him we’re dead, lifeless, oblivious to Him. (Ep 2:5) If we happen to find ourselves aware of Him, and of our need for Him, and if we’re willing to seek His face and submit to Him (He 11:6), this itself is the gift of God. (2Ti 2:25) If we pursue Him, He will give us the evidence we need and lead us into all truth (Mt 7:7-8), into Himself.
The blindness of the fallen nature is no excuse to be imprecise or irresponsible in our thinking, or in our efforts to reason with others. We should do our level best to present the truth as clearly and as articulately as we are able. (1Pe 3:15) Yet we must keep in mind that it isn’t the power and wisdom of our argument that will win the day, but the power of God. (1Co 2:5) He will enlighten those He chooses according to His pleasure and in His time.
