Certainly many congregations do not consider that they should obtain deep knowledge of the word of God, because the word that says:
who has made us enough to be ministers of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life.
2 Corinthians 3: 6
and do not consider what God says in his word:
My people are destroyed for lack of knowledge;
because you have rejected knowledge,
I reject you from being a priest to me.
And since you have forgotten the law of your God,
I will also forget your children.
Hosea 4: 6
