I think it is so interesting how the author of this Psalm says “teach me.” That is the truth of it. God must teach us His ways and His truth. The Spirit is the one that opens the Word to us. May He burn His Word into our hearts and minds forever, so that we obey it and follow the Lord every moment.
I think part of the purpose of living through this life is to be taught by God. In eternity, how would we ever have an understanding of God’s grace for example, unless we directly experienced it. How would we understand being made perfect and having a good, perfect nature and the greatness of obeying God if we hadn’t experienced the opposite.
The writer of Hebrews states, “Although he [Jesus] was a son, he learned obedience from what he suffered” (Heb 5:8).
Like Jesus, we will learn trust and obedience through the lessons God gives us, so patiently endure all things with faith and obedience.
Not to go off on a tangent, but it is interesting too that Jesus learned obedience from suffering. He is God after all and does not have to obey anyone. Yet, He obeyed the father’s will through the experience of the Passion. And prior to that in the Garden, He asked the Father if the cup could pass from Him, but He asked for the Father’s will instead of His own. So obedience is laying aside our will (desires, purpose, selfishness) and letting the will of the Lord be our will.
