I know, and you do too, that You Tube is a terrible place to learn theology. Everyone is an expert, and no one knows anything. All you get are crazy AI generated ideas based on God knows what. One red flag is when you find a theologian who spend more time talking about what the author meant and his context in his world. What was going on around him that he saw truth in this perspective. In claiming to be wise they reveal themselves as fools.
Let's reaffirm what the Bible has to say about this.
"holy men of God spoke as they were moved by the Holy Spirit." 2Pet.1:21
The Bible contains God's word. It is God's self-revelation of Himself. It is not the writings of men compiled into one volume. It is in truth the word of God.
"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness." 2Tim.3:16
The task of every person is to read and understand the Bible. To pay the price for truth.
"Buy the truth and do not sell it" Prov.23:23
When you hear a sermon that moves you to action or when you get revelation from scripture, you are dealing with men who have paid a price to understand truth.
I find that familiarity breeds contempt. When you get bored with the Bible you begin to look for new ideas. You try to understand the person who God used to speak rather than God and His word. The Bible is not about Moses or David or Paul. It's about God.
The secret to staying on track is gratitude. Being grateful for the Bible as it is. Being grateful to God for what He has done. Gratitude is the antidote to boredom.
