I think these things happen because "faith cometh by hearing"
I think that the above holds true for pretty much everyone to some degree.What you hear the most is what you will,in your heart,trust the most and what you trust deep in your heart is what will direct the way you think.And I suppose the way we think would determine to a large degree how we see the world.It's why propaganda works.
The "god of this world" has been busy undermining believers trust,deep down inside,of the reality of God's word by bombarding the senses with everything including the kitchen sink to the contrary.He's been doing it a long time and the effectiveness of his railing has expoded in the last century.To the point where we are practically swimming in an anti-christ current.
No wonder Jesus said the work of God is to believe!Because most everything in this world incuding our own deceitfull heart is against God and is against confronting that which is "a discerner of the thoughts and intents of the heart" It's sad so many have had their spiritual senses dulled to the point where we may well be living on the very cusp of the most stupendous event in the history of the cosmos and many are too busy with religion to see it.
We need to "test all things" big time and hold every thought captive.Hold it,turn it around and give it a good inspection before allowing it to continue on down to reside with the rest of our 'baggage'.If we don't our own heart will be slowly but surely lead to man's wisdom.In spite of what we may think we believe it's what we do that will tell us what's going on in our heart."For as a man thinketh in his heart,so he is"
The so-called christian left and no doubt the rest of us,need to check what we are hearing 'cause wether we do or not it will eventually end up determining to a big degree what we really do have faith in.And that sort of deep down faith can't be faked,for good or for bad.
Sorry for the rant but it's better than turnin' blue.
