'Sanctified' in the Bible

because both the one who sanctifies and those who are being sanctified all have the same Father. That is why Jesus is not ashamed to call them brothers

By God's will we have been sanctified once and for all through the sacrifice of the body of Jesus, the Messiah.

For by a single offering he has perfected for all time those who are being sanctified.

How much more severe a punishment do you think that person deserves who tramples on God's Son, treats as common the blood of the covenant by which it was sanctified, and insults the Spirit of grace?
