What does it mean that faith establishes the law?

Romans 3:31 KJV

“Do we then make void the law through faith? God forbid: yea, we establish the law.”

The Law establishes the need for “faith” as the KEY element of salvation; that is, the initiation of New Covenant relationship with the Father, as the law demands absolute perfection (James 2:10) if righteousness (a right standing) with the Father is to be attained through law-keeping – BUT – there is a very relevant problem, all of humanity is under the curse of sin (Romans 5:12; Romans 3:23); therefore, humanity has already violated the law; therefore, the law curses anyone seeking righteousness through obedience to it (Galatians 3:10); fortunately, the Father did for us what we could not do for ourselves through vain attempts to keep the law; that is, the Father commissioned the Son, Jesus Christ, to enter the Realm of Time born of the virgin seed thereby bypassing the sin-nature of Adam; therefore, Jesus walked in sinless perfection before the Father and in doing so, Jesus fulfilled every jot and tittle of the law’s moral mandates and through His sinless perfection, Jesus made Himself the spotless Lamb of Elohim who takes away the sin of the World (John 1:29-32; 1 Peter 1:18-19; 1 John 2:2) as Jesus provided you and me acceptable blood atonement for our sin as mandated by Leviticus 17:11; therefore, anyone who believes in Jesus by “faith” in Him as their Messiah who died for them (John 3; Romans 10:9-10), that person so believing receives the indwelling Holy Spirit as Guarantor of Covenant with the Father (Ephesians 1:13-14) and that person is declared “not guilty” by covenant promise (Hebrews 8:12); this, by faith in Jesus as Messiah which is something the law could never do as the law is weakened by the sin-nature (Romans 8:1-6).

Faith establishes the impotency of the law to save (Romans 8 ) and faith establishes the truism that no one is justified through law as law simply defines sin but provides no form of acceptable atonement (Romans 3:20); therefore, the Father’s standard for righteousness (a right standing) with Him is absolute perfection (James 2:10) and that perfection can only manifest in our life via the imputation-gifting of Jesus’ righteousness over our life by FAITH (2 Corinthians 5:21); therefore, the law has become a tutor to point us to our need for Jesus by faith (Galatians 3:24-25); therefore, we walk by the Spirit, we serve through the Spirit by faith and not in oldness of the letter (Galatians 5; Romans 7:6).
