Hebrews 6:1, 12

So let us stop going over the basic teachings about Christ again and again. Let us go on instead and become mature in our understanding. Surely we don’t need to start again with the fundamental importance of repenting from evil deeds and placing our faith in God.

Then you will not become spiritually dull and indifferent. Instead, you will follow the example of those who are going to inherit God’s promises because of their faith and endurance.
