Because they're carnal Christians, still hanging on to their ego instead of answering with the love of God.
'Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things. Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away', 1 Cor 13:4-8.
It seems w/o the love of God, one may not know Him that well or who He is(Love). Our duty is to be patient and wise🙏, lol.
I have a feeling its mostly to do with taming the tongue. Not in a way you would imagine but taming the tongue as in appreciating the tongue needs to be able to taste divinely, and without it being able to taste divinely it goes crazy
You knows the tongue is beautiful really, I mean it really does feel the taste buds, in such a way that when you hold on to your tongue, you can just know you know, i mean just position your tongue and feel your tongue on your lips, you know without speaking for oh I don't know five minutes, and just imagine what it would be like to speak something nice, whilst tasting you taste buds,
But as Saying goes well you are what you eat, so I would imagine that what you import into your body also determines how well or taste buds taste, and how well your tongue can pick up under taste if you know what I mean .
I mean if you only put in what is most agreeable to the body then I would imagine your inner taste can become quite divine really, you know I mean I think the hard thing is people discovering what is desirable to their bodies over time I would imagine.
Then I suppose once you get the balance right you know, you can really taste this and feel the difference 😊
