A wrong understanding is interested in precisionism. That is it tries to say that the Bible can't be telling the truth if it says that Jesus was such and such a distance from some place or other and in fact the distance is off by 15% or something like that. There are all kinds of grounded figures and so forth.

It's not as if the New Testament writers came along and said, "The culmination of Old Testament books is more books, New Testament books." In some ways they thought instead of the culmination of Old Testament books being Christ himself, the word incarnate as the opening verses of Hebrews 1 put it. In the past God spoke to the fathers by the prophets, but in these last days he has spoken to us by his son and the son is revelation.

Sin corrupts even our good deeds. We injure our shoulder trying to pat ourselves on the back.

"Biblical theology" refers to something more precise than theology that is faithful to the Bible. It might be helpful to draw a contrast: at the risk of oversimplification, systematic theology tends to organize theology topically and with an eye cast on its contemporary relevance, while biblical theology tends to organize the same biblical material so that it is easier to see the distinctive contribution of each biblical book and human author, and to trace the trajectories of themes across the Bible so we see how the books of the Bible hold together.

The person who prays more in public than in private reveals that he is less interested in God's approval than in human praise. Not piety but a reputation for piety is his concern.

The person who loves his life will lose it: it could not be otherwise, for to love one's life is a fundamental denial of God's sovereignty, of God's rights, and a brazen elevation of self to the apogee of one's perception, and therefore an idolatrous focus on self, which is the heart of all sin

Hell is not filled with people who are deeply sorry for their sins. It is filled with people who for all eternity still shake their puny fist in the face of God Almighty.
