Charles H. Spurgeon on Psalms 119:2

Testimonies. The word of God is called his testimony, not only because it testifies his will concerning his service, but also his favour and goodwill concerning his own in Christ Jesus. If God's word were no more than a law, yet were we bound to obey it, because we are his creatures; but since it is also a testimony of his love, wherein as a father he witnesseth his favour towards his children, we are doubly inexcusable if we do not most joyfully embrace it. William Cowper.
