One of the things that came out of the time today is another project. I have heard snippits of other Psalms as I listen to Psalm 119. One of the projects that I am going to pursue is to work through Psalm 119 section by section and connect the themes in that section to other Psalms.
I started that this evening. The idea is to spend a week on each section. So I started looking more closely this evening at Psalm 119:1 - 8. I noticed something that I had not seen before. Verses 1 - 4 describe the benefit of obedience, being blessed. Verses 5 - 8 record David asking the Lord to help him, establish him so that he can obey. David realized that on his own he was not able to really keep the Lord's statutes. In this he predated Paul in Romans 7.
By the way that theme, beseeching the Lord for help to follow Him, is a consistent theme through 119.
So it would seem that our ability to obey, like our faith, may be a gift from God.
