Isa 61:10, 1 Cor 6:11, 2 Cor 5:17, Gal 3:27, Col 3:10, Rev 7:14
In the Old Testament, Satan sued Joshua, the high priest representing the people of Israel who had sinned. But God took off the clothes of the high priest Joshua, who was wearing dirty clothes, and took away his sins and put on beautiful clothes. (Zec 3:1-5)
Zec 3:1 And he shewed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to resist him. 2 And the Lord said unto Satan, The Lord rebuke thee, O Satan; even the Lord that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire? 3 Now Joshua was clothed with filthy garments, and stood before the angel. 4 And he answered and spake unto those that stood before him, saying, Take away the filthy garments from him. And unto him he said, Behold, I have caused thine iniquity to pass from thee, and I will clothe thee with change of raiment. 5 And I said, Let them set a fair mitre upon his head. So they set a fair mitre upon his head, and clothed him with garments. And the angel of the Lord stood by.
In the Old Testament, God promised to clothe us with the garments of salvation. (Isa 61:10)
Isa 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.
We have been sanctified through the forgiveness of sins through Christ. (1 Cor 6:11, 2 Cor 5:17, Gal 3:27, Col 3:10, Rev 7:14)
1 Cor 6:11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
2 Cor 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Gal 3:27 For as many of you as have been baptized into Christ have put on Christ.
Col 3:10 And have put on the new man, which is renewed in knowledge after the image of him that created him:
Rev 7:14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
