Martin Luther on Faith and Reading the Word

So we continually teach that the knowledge of Christ and of faith is not a human work but simply the gift of God, who creates faith and maintains it in us. Just as he first gives faith to us through the Word, so afterwards he exercises and increases it, strengthens it, and makes it perfect in us by the Word. Therefore, the greatest service that we can give to God, the very sabbath of sabbaths, is to exercise ourselves in true godliness, diligently listening to the Word and reading it.

Conversely, there is nothing more dangerous than to be weary of the Word. Anyone who is so cold that he thinks he knows enough and begins gradually to loathe the Word has lost Christ and the Gospel, and what he thinks he knows, he attains only by speculation.   (Commentary on Galatians 1:11, 12).
