"Again a voice came to him a second time, "What God has cleansed, no longer consider unholy.""
Are you holy? Have you been washed by the blood of Jesus Christ? Has the cross taken away all of your sins?
Truly if you are in Christ by faith in his blood then you are holy. God has pardoned you. Because you believed God has done what he has promised, it has been credited to you as righteousness.(Gen 15:6) So what God has cleansed, no longer consider unholy. You are a new creation (2Cor 5:17) not because of anything you did, but because God cleansed you. You are holy because God is holy and is the one who makes you holy. (Lev 21:7,15,23;22:9,16,32)
So do not blaspheme God by calling what is holy unholy. If you have believed in Christ, do not dare to deny what Christ has done through confessing your sinful nature. You are no longer sinners, but you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God. (1Cor 6:11) You have died to it,(Rom 6:2) how can you still confess to be in it? Profess that "Though I was once a sinner, Christ took away my sin, and by his Power I am kept holy, pure, and blameless" lest you deny the reality of that which justifies you, Christ Jesus and him crucified.
Or do you not believe the gospel of grace so generously poured out on your behalf?
