When it comes to driving a vehicle, there are many rules involved. You must stop at every stop sign, you must wait your turn at a four-way stop, you must obey persons who direct traffic, you are commanded to obey speed limit signs.
Arguably, most of these rules are necessary. If you habitually refuse to stop at stop signs, you will probably receive a substantial number of traffic tickets, not to mention the endangering of your own life and the lives of others. 'Waiting your turn' at a four-way stop is basic courtesy as well as a prevention of personal injury. Thus, many of these rules are necessary.
But it would be extreme to say these rules are wonderful. Sitting in a traffic jam is not a wonderful experience---unless you enjoy squandering time and consuming fuel. American drivers have varied opinions as to what is a fair speed limit and what is a silly speed limit for particular areas. Many Americans on tight schedules evaluate certain speed limits as restrictive and stupid, not wonderful.
The Psalmist, though, evaluated the testimonies and commands of God as being wonderful:
"Your testimonies are wonderful; Therefore my soul keeps them. The entrance of Your words
gives light; It gives understanding to the simple. I opened my mouth and panted, For I longed
for Your commandments." (Ps.119:129-131)
The Psalmist interpreted God's words as not only necessary, but wonderful. Why are they wonderful? Because the wonderful Author of salvation has given us His Word. The Divine Author of Scripture has revealed truths in line with His wonderful character.
The Psalmist declared: "My soul keeps them." We Christians devote ourselves to the directives of God because we trust and love the wonderful One Who has given them to us.
"You are good, and do good; Teach me Your statutes."---Ps.119:68.
