I see two basic approaches or ways of conveying what we call the 'truth' - one way is acerbic, and perhaps the other way is gentle or kind. Perhaps the truth is also both, as perhaps the exoteric layer of the truth is kinder than the esoteric layer. Perhaps the truth is kinder to beginners, or to the general public laymen.
I think that even if the 'truth' is 'acerbic,' we should probably strive to make it kind. I don't think that truth/honesty has to be so raw even if it wants to be, as the ascerbic path seems like it has the potential to be discouraging. Perhaps the truth needn't melt away falsity without understanding and consideration
Still, if the truth is packaged with too much fluff, perhaps the seekers of it will be ill trained when it matters. I don't know
Religion or even science doesn't make it easy to distinguish which 'truth' you wish to display. Let me share an example if I may to illustrate this. Let say I really want to convince my friend that the sky is blue, when in his 'truth' the sky is actually a light gray. Now, we must state that 'truth' should be universal that the sky is in fact blue, because that is what everyone would classify it as and we have accepted it, but it just turns that your friend has decided to go a step further and readdress this slight tone difference should be acknowledged for it is truth. There are a few ways you could handle this situation. One is let your friend live believing differently than you and perhaps have them live in ignorance their whole lives, hoping that one day they would see the light of day 2. Act against their truth, giving them facts, science articles, and testimonials along with a possible ultimatum to believe how you and everyone else believes or you want nothing to do with them. or 3. Accept their beliefs as something they hold onto, having it in consideration for a possible truth. The first and the third most likely still result you being friends. the second gives the option of removing all further communication with you and your ideas.
In reality, we might not know exactly what truth is. Most of everything we think we know as truth is actually 99.9999% true. Our brains fill in the rest of the .00001% so we can move on with life and not deal with it. 2+2 doesn't always equal 4. In fact, mathematically, I think we could manipulate that equation to equal almost anything we would like to given the time and energy to. But for time sake we don't. My point is, unless we had the authority and power of God who created everything, we can't begin to profess truth to someone else. Their truth may be different than our truth but that doesn't mean it is wrong or right. In the end, however, truth is out there just like keys unlocking universal doors to absolute knowledge. The One to hold those keys is God or the Creator. If we pray to Him with sincereness and desire to know what is true or not, He will give it to you. Why? Probably cause he cares about you. Probably cause he created this playground of knowledge in the first place, to discover it. Once we receive truth, it becomes the sweetest of all things we could experience. Every person can have that experience, but not have it at the same time, in the same place. The journey is different for everyone.
