Sealed by the Spirit

2 Co 1:21 Now He who establishes us with you in Christ and anointed us is God, 22 who also sealed <4972> us and gave us the Spirit in our hearts as a pledge.

Eph 1:13 In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed <4972> in Him with the Holy Spirit of promise,

Eph 4:30 Do not grieve the Holy Spirit of God, by whom you were sealed <4972> for the day of redemption.

Revelation 7:1-9 describes the sealing of 144,000 members of the tribes of Israel:

Re 7:3 saying, "Do not harm the earth or the sea or the trees until we have sealed <4972> the bond-servants of our God on their foreheads."

Revelation 14 says that this group has the father’s name in their foreheads:

1 ¶ Then I looked, and behold, the Lamb was standing on Mount Zion, and with Him one hundred and forty-four thousand, having His name and the name of His Father written on their foreheads.

Those who serve God in the New Jerusalem are portrayed as having God’s name in their forehead:

3 There will no longer be any curse; and the throne of God and of the Lamb will be in it, and His bond-servants will serve Him;
4 they will see His face, and His name will be on their foreheads.

On the one hand, Scripture is clear that the Holy Spirit seals believers. On the other hand, it also clearly describes the seal as the Father’s name.
