Hosea 4:6

My people are destroyed for a lack of knowledge (of My law, where I reveal My will). Because you (the priestly nation) have rejected knowledge, I will also reject you from being My priest. Since you have forgotten the law of your God. I will also forget your children.

Jesus came to this earth to redeem us and restore our authority and dominion. The Word is specific about us speaking to the mountain, and it will obey us. If we are not using the Word or we don’t know the Word, the mountain stays put. If we reject the knowledge God gave us, God can’t help us.
