What is the "it" you mention above? If you can't tell us that, then you tell us nothing - a requirement without
a solution. You also need to inform us as to the frequency by which the "it" must be satisfied in order to have been saved. Having stated the above, you became obliged to enumerate both answers in detail so that we may satisfy them, and/or, to know that we have satisfied them, otherwise, we will have no standard to compare/measure ourselves against.
"It" referred back to God's law, which consists of the laws that God has commanded. I've said nothing about needed to to obey God's law with a certain frequency in order to become saved, but rather I said that God graciously teaching his to obey His law is the way that he is giving us His gift of salvation. In Titus 2:11-13, our salvation is described as being trained by grace to do what is godly, righteous, and good, and to renounce doing what is ungodly, so we are not required to have first done those works in order to become saved as the result or as the result of having first been saved, but rather God graciously teaching us to do those works in obedience to His law is the way that He is giving us His gift of salvation.
I'm incapable of satisfying those. Thankfully, through Christ, I don't need to.
The Psalms express an extremely positive view of obeying God's law, such as with David repeatedly saying that he loved it and delighted in obeying it, so if we believe that the Psalms are Scripture, then we also need to believe that they express a correct view of obeying God's law, and that we should share it. For example, in Psalms 1:1-2, blessed are those who delight in the law of the Lord and who mediate on it day and night, so we can't believe in the truth of these words as Scripture while not allowing them to shape our view of getting to obey God's law. So you being thankful that you don't need to satisfy God's law is incompatible with the view that the Psalms are Scripture. In 1 John 2:6, it says that those who are in Christ are obligated to walk in the same way he walked, not that those who are in Christ don't need to.
So, let me see if I have this straight: according to you, we prove that we are not under law.... by keeping law which we are not under, and by keeping law which we are not under, we thereby prove that we are saved; otherwise, if we don't keep law that we are not under we prove we are not saved. That about it or have I misunderstood something?
What does that have to do with what I've said?
While I agree that we are not under the law, Paul spoke about mutable different categories of law other than the Law of God, such as the law of sin and works of the law, so it is important to correctly identify which law he was referring to us as not being under. For example, in Romans 7:25-8:2, Paul contrasted the Law of God with the law of sin and contrasted the Law of the Spirit of Life with the law of sin and death. In Romans 3:27, Paul contrasted a law of works with a law of faith, and in Romans 3:31 and Galatians 3:10-12, Paul said that our faith upholds God's law in contrast with saying that works of the law are not of faith.
The Law of God leads us to do what is holy, righteous, and good, so it is a law where holiness, righteousness, and goodness have dominion over us, whereas the law of sin stirs up sinful passions in order to bear fruit unto death (Romans 7:5), so it is a law where sin had dominion over us, and Romans 6:14 describes the law that we aren't under as being a law where sin had dominion over us. In Romans 6:15, being under grace does not mean that we are permitted to sin, and in Romans 3:20, it is by God's law that we have knowledge of what sin is, so we are still under the Law of God, but are not under the law of sin. Moreover, everything else in Romans 6 speaks in favor of obedience to the Law of God and against sin. God is sovereign, so we are all under His law.
Jesus saves us from our sin (Matthew 1:21) and sin is the transgression of the Law of God (1 John 3:4), so Jesus leading us to be an obeyer of the Law of God is intrinsically the way that he is giving us his gift of saving us from not being an obeyer of the Law of God. The position that we are not under God's law is the position that we do not need to refrain from sin, that we do not need salvation from sin, and that we do not need Jesus to have given himself to redeem us from all lawlessness.
