Psalms 119:80

We may regard this inspired prayer as containing within itself the assurance that those who keep close to the Word of God shall never have cause to be ashamed of doing so.

See, the prayer is for soundness of heart. A sound creed is good, a sound judgment concerning it is better, but a sound heart toward the truth is best of all. We must love the truth, feel the truth, and obey the truth, otherwise we are not truly sound in God's statutes. Are there many in these evil days who are sound? Oh, that the writer and the reader may be two of this sort!
