Psalm 119 starts off with a promise that the person who lives according to God’s (Yahweh) instruction will be happy because his way will be blameless (verse 1).
The Psalmist pronounces his struggles to follow what God has commanded. See verse 4 - “You have commanded” and verse 5 “if only my ways were committed to keeping Your statutes”. It is a great point that he makes - being committed to following God’s ways. I look at this statement as an example of putting on snow skis or water skis. To have a successful event one must have his/her feet securely set in the skis. Once your feet are secure, the skier is guaranteed to keep you on the path. Now, in my example, I am not taking into consideration the person’s skills in skiing or the condition of the path. The point I want to make is this - In order for our lives to reflect the truths found in Scripture (being blameless, being happy, finding success, etc.) we must be committed to staying in the will of God. We must vow to stay “strapped” in.
Ps 119: 8 “I will keep your statutes…”
