Let us go forward, then, to mature teaching and leave behind us the first lessons of the Christian message. We should not lay again the foundation of turning away from useless works and believing in God;
For how can those who abandon their faith be brought back to repent again? They were once in God's light; they tasted heaven's gift and received their share of the Holy Spirit;
And then they abandoned their faith! It is impossible to bring them back to repent again, because they are again crucifying the Son of God and exposing him to public shame.
When God made his promise to Abraham, he made a vow to do what he had promised. Since there was no one greater than himself, he used his own name when he made his vow.
To those who were to receive what he promised, God wanted to make it very clear that he would never change his purpose; so he added his vow to the promise.
There are these two things, then, that cannot change and about which God cannot lie. So we who have found safety with him are greatly encouraged to hold firmly to the hope placed before us.
