This episode addresses the means by which God would establish the psalmist's ways to keep His statutes. (5-6) These verses capture the goal of the entire psalm. On the road to receiving God's assistance, the psalmist acknowledges his faulty ways and repents: "I consider my ways and turn my feet to your testimonies." (59) This statement indicates repentance and directs the psalmist's to God's testimonies. Throughout Psalm 119 eight expressions of God's way (way, law, precepts, ordinances, commandments, testimonies, word, statutes) become the central focus of the psalmist. The more the psalmist reflects on God's testimonies, statutes, etc., the more the way of God is established in his life. In like manner, NT believers are called to consider God's testimonies, i.e., His kindnesses, and the reflection leads to repentance. (Rom. 2:4) The more we reflect on all the spiritual blessings we have in Christ, the Son Himself Who is the Way, becomes our way of life. God establishes our way as we abide in the Way.
Keeping the Law, through Christ
This initial episode answers the question right from Psalm 119:5-6, which I believe summarizes the main theme of the entire psalm. "Oh that my ways may be established to keep your statutes! Then I will not be ashamed when I look upon all your commandments." Since the question mostly deals with how Psalm 119 should be applied to NT believers, the episode deals with a common misunderstanding of the importance of the Law for Christians. Some claim that Christians are not under the moral law based, based on Christ having fulfilled it for us. While our acceptance in God's sight is completely based on Christ's perfect adherence to the Law, coupled with His substitutionary death, Christians are obliged to keep the moral law by abiding in Christ. The sum of the Law is love of God and neighbor, and the New Testament constantly holds believers accountable to observe these commandments THROUGH abiding in Christ. This then is the clearest application of Psalm 119 to NT believers, that God would help establish our ways to abide in Christ, resulting in keeping God's moral law.
Biblical repentance goes deeper than you might think
This episode goes deeper into the depth of spiritual death in which all mankind participates. Spiritual death does not simply refer to outward transgressions, but also describes the spiritual state of the inner man that produced them. Paul says in Colossians 2:13 that we were "dead in our trespasses AND the uncircumcision of our flesh," indicating that spiritual death is descriptive of both the acts themselves (dead works) and the one who is uncircumcised in the flesh. So when one repents of dead works, he also has a change of mind about the self that produced them characterized by death. The solution to spiritual deadness is the circumcision of Christ, the supernatural cutting away of the flesh in regeneration.
