Ephesians 2:8-9
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
Christ doesn't lie, ever. Christ is the Truth. You know that already. It is by Christ's law-keeping that the many are made righteous, through the shedding of His righteous blood. This is the Christian's confidence and all his hope is founded upon Jesus Christ the Righteous, and Him crucified. He died for sinners, and rose again for our justification. By His stripes we are healed.
Having begun in the Spirit, we are not now being made perfect by the flesh. The flesh profits nothing. It is the Spirit that gives life. The Spirit is He who testifies of the Lord Jesus Christ. The Spirit is the Author of the Scriptures. Humble yourselves under the mighty hand of God, that He may exalt you in due time. For the LORD resists the proud, but gives grace to the humble. The law of faith excludes boasting. Looking into the perfect law of liberty, we behold His face, as in a mirror, becoming like unto His glorious image. Not by fleshly ordinances of "Do not touch", "Do not taste", "Do not handle", for Christ is the end of the law for righteousness to everyone that believes.
The one who loves Christ will seek to obey Christ in all things. Those born of God's Spirit have the Spirit abiding in them and do not need that any should teach them to love God, for they will love Christ according to the Spirit that is in them. Nor can any man compel another to believe by teaching law, for the law cannot save. The law reveals sin and speaks to those without Christ, and those who seek to be justified by law will not obtain that which they seek.
Galatians 3:10-11
10 For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
For by grace are ye saved, through faith, and that not of yourself. It is the gift of God. Free Sovereign grace is given to hell-deserving sinners. In me, that is in my flesh, dwelleth no good thing. No good thing. It is only in looking to Christ, the Author and Perfecter of my faith that I live by faith. Faith in Christ. Faith in His blood, in His righteous life, His sacrificial, propitious, atoning death, His resurrection from the dead for my justification, His holiness my own. Union with Christ is necessary. All the merits are of Christ. There is no merit in my law-keeping. Christ is all and in all. He is my righteousness, my sanctification and redemption. It is His righteousness and not my own that avails for me. God bless every one.
