Martin Luther

The devil and temptations also do give occasion unto us somewhat to learn and understand the Scriptures by experience and practice. Without trials and temptations we should never understand anything thereof; no, not although we diligently read and heard the same. The Holy Spirit must be the only master and tutor to teach us therein, and let youth and scholars not be ashamed to learn of this tutor. When I find myself in temptation, then I quickly lay hold and fasten on some text in the Bible which Christ Jesus layeth before me, namely, that he died for me, from whence I have and receive comfort.
