Our Speaker during Family Bible Hour was Dr. Dale Schreiber.   He continued his series on the Blessings of Salvation.  One of the blessings received by a person who is saved through the finished work on the cross by the Lord Jesus Christ of Nazareth  is the sealing of the Holy Spirit.  The use of a seal during N.T. times  indicate ownership, underlies the importance of what was sealed, identifies the owner, and guarantees the security of the item sealed.  The same blessings are bestowed by the Holy Spirit on all believers as a testimony to the finished work of the Lord Jesus Christ.  For more on this excellent message, see the DVD. Check with Romy if you're interested.
Dr Schreiber's whole series on the Blessings of Salvation is also available for your reading enjoyment --  Please see Bill C.

And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.  ~ Ephesians 4:30

Now he which stablisheth us with you in Christ, and hath anointed us, is God: Who hath also sealed us, and given the earnest of the Spirit in our hearts.  ~ 2 Corinthian 1:21-22
