Verse 105 is the motto of Scripture Union. It is plain that we must be doers of the Word of God and not hearers only. This New Testament teaching is an Old Testament one.
Verse 90 and 91 are very interesting, as they do not contain any of the words we looked at when first starting Psalm 119 (God’s law, testimonies, ways, precepts, statutes, commandments, rules).
They don’t contain the specific words.
“Your faithfulness endures to all generations; you have established the earth, and it stands fast. By your appointment they stand this day, for all things are your servants.”
It speaks to v89 too, the HEAVENS and the EARTH.
So we know that by His word God CREATED the heavens and the earth (Gen 1).
All the words above are words that speak of God’s word. His law. His precepts. Etc.
So God created with His word.
But more! We know that Jesus Himself was there in the beginning (John 1), that He is the Word become flesh, so that by Him God created the heavens and the earth, AND He is the energy that SUSTAINS (“By your appointment they stand …”) all of creation too.
So while v90 and 91 don’t have the specific words in them that we have seen, they clearly speak of God’s word. Of Jesus.
Hallelujah, what a Saviour!
