All those who are trying to keep the Law of Moses for any part of their salvation are fallen from Grace. Whosoever they are that try to mix the salvation that Christ has accomplished with the deeds of the law; Paul says that Christ will profit them nothing (Galatians 5:2-4). It does not matter if their obedience is for their Justification, Righteousness, Redemption or Sanctification, as they are ignorant of the righteousness of God and know not the Lord Jesus Christ (Romans 10:1-4).
The law of God is not a guide for the believer’s life, but it is the Law of God. If anyone is under the law, he is then subject to obey the whole law in every part. If that man fails in one point, he is cursed and guilty of the whole law (Galatians 3:10; James 2:10). Therefore by the deeds of the law shall no flesh be justified in God’s sight. All have sinned and have fallen short of the glory of God. None are good, none are righteous, none seek after God, and none shall glory in the presence of God by his obedience (Romans 3:9-28).
Therefore the gospel of Jesus Christ is the best news for such ruined, hopeless, and vile sinners who have not, and cannot ever obtain righteousness by their obedience. For Jesus Christ has for sinners honored, magnified and obeyed the law in the stead of all those the Father gave to Him (Isaiah 42:21; Gal. 4:4). The law of God that demanded our perfect obedience Jesus has fulfilled in that God has said: “This is my beloved Son in whom I am well pleased.” Jesus has satisfied the Justice of the law that demanded our death. For He by His one offering hath obtained eternal redemption for us. Jesus by His one offering hath perfected forever them that are sanctified.
Have you believed on the Son of God? Have you trusted on Him alone as all your righteousness, all your justification, all your wisdom, all your redemption and all your sanctification? Then rejoice, for Christ has freed us from the law of sin and death. In Christ we are righteous, we are redeemed, we are sanctified, and we are justified before God. Therefore Jesus our Lord and our Savior is the END of the Law for righteousness to every one that believeth.
Oh, believe on Christ and lean on Him! Rest all the weight of your soul on Him. To lean on Christ requires no strength from us but rather our weakness. To lean on Christ is to forsake all hopes of salvation by the law, seeing that all the Law witnessed of Him and His perfect work.
