Of coaurse it is.
Never confuse justification with sanctification.
Hebrews 10:10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all. 11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: 12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; 13 From henceforth expecting till his enemies be made his footstool. 14 For by one offering he hath perfected for ever them that are sanctified. 1 Corinthians 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.
Hebrews 10:14 For by one offering he hath perfected for ever them that are sanctified.
Rom. 5:1, "therefore having been justified by faith, we have peace with God through our Lord Jesus Christ,"
It's a done deal.
