Charles H. Spurgeon on Psalms 119:138

Thy testimonies. The word of God is called his testimony, both because it testifies his will, which he will have us to do; as also because it testifies unto men truly what shall become of them, whether good or evil. Men by nature are curious to know their end, rather than careful to mend their life; and for this cause seek answers where they never get good: but if they would know, let them go to the word and testimony; they need not to seek any other oracle. If the word of God testify good things unto them, they have cause to rejoice; if otherwise it witnesseth evil unto them, let them haste to prevent it, or else it will assuredly overtake them. William Cowper.
