Anything that soils our robes of righteousness is a sin.
That is my definition of sin, not something anyone else has to agree with. So let us move on to the issue of having a right standing before God the Father.
Romans 3:10 As it is written, There is none righteous, no, not one:
Given this is true, how can I say that I even have a robe of righteousness?
Romans 3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Paul in his letter to the Romans has laid out some very rational arguments between Romans 3:10 and 3:20 that states why we are not righteous but here in verse 20 he adds a qualifying word that makes everything right in God’s eyes. That word is justified. Justification Is an accounting term where the ledger of debt is paid moving us out of the red (debt) and into the black.
No deed of the law, including total obedience to the law, brings us into a relationship with God the Father that is acceptable in His eyes. If we think that obeying all the law will bring about righteousness, we are mistaken. So how do we obtain these robes of righteousness?
Isaiah 61:10 I will greatly rejoice in the Lord, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels.
God provides the robes of righteousness to prepare us for the wedding.
Philippians 3:9 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
So faith in Christ is how we will be issued robes of righteousness, to become betrothed to the Son. God would not create a law that He Himself would not keep.
Exodus 21:9 And if he have betrothed her unto his son, he shall deal with her after the manner of daughters.
2 Corinthians 11:2 For I feel a divine jealousy for you, since I betrothed you to one husband, to present you as a pure virgin to Christ.
Wearing those robes only makes us look righteous in God’s eyes. Underneath our flesh still touches these robes and soils them because we have not been translated into our incorruptible state of being. Yet!
