Charles H. Spurgeon on Psalms 119:112

I have inclined my heart to perform thy statutes alway, etc. In the former verse he showed his faith, and his joy which came thereof; now he showeth that here in this joy he will keep the commandments; whereby he showeth that this was a true joy, because it wrought a care to do good. For if we believe the promises truly, then we also love the commandments, otherwise faith is vain; a care to live a godly life nourisheth faith in God's promises. Here is the cause then why many regard not the word and sacraments; or if they do a little, it is to no purpose, because they labour not to keep the commandments. For unless they have care to do this, the word of God to them cannot be profitable, nor the sacraments sacred. Richard Greenham.
