You still have not refuted the Scriptures I posted.
Ephesians 1:12-14
13 In Him, you also, after listening to the message of truth, the gospel of your salvation-- having also believed, you were sealed in Him with the Holy Spirit of promise, 14 who is given as a pledge of our inheritance, with a view to the redemption of God's own possession, to the praise of His glory. NAS
Ephesians 4:30
30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. NAS
Where do you get the idea the 4th Commandment is the seal of anything?
