A weak understanding of what the Bible says about sin is tied to a weak understanding of what the Bible says is achieved by the cross.

We are lost when human opinion means more to us than God’s.

Effectiveness in teaching the Bible is purchased at the price of much study, some of it lonely, all of it tiring.

Some have argued that the Christian notion of Scripture is not epistemologically sustainable. It's not philosophically possible with rigor to uphold the Christian understanding of Scripture.

To worship God 'in spirit and in truth' is first and foremost a way of saying that we must worship God by means of Christ.

The important thing, Jesus is saying (in Matthew 5:33-37), is to tell the truth and keep one's pledges without insisting that a certain form of words must be used if it is to be binding. No oath is necessary for the truthful person... Their word is so reliable that nothing more than a statement is needed from them.
