The Seal of God

The Seal of God (7:3):

No one can enter Heaven without the seal of God on the foreheads. And God will give to every person ever born all the opportunities to be sealed, "Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God." (7:3)... God wants every person ever born to go to Heaven (1Tim.2:4)...God actually made every person to go to Heaven... but anyone can end up in Hell, if he is not faithful!.
The Seal is not a tattoo in the skin of the forehead, but the infusion of the "Love of God", manifested by truthfulness in the head and by generosity in the hand, in contraposition of the Seal of Satan which is the infusion of "the hate of Satan", manifested of lies in the head and greed in the hand. See a larger comment on The Mark.

The Sealing of the Christians in Baptism:
- Having believed, you were sealed with the Holy Spirit of promise. (Ephesians 1:13).
- And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. (Ephesians 4:30).
- God, who also has sealed us and given us the Spirit in our hearts as a guarantee. (2 Corinthians 1:21-22).
This is the first time the Seal of God is mentioned in Revelation, and it will appear again in 9:4, 14:1, 22:4... the Seal of the Beast is mentioned in 14:9,11, 16:2, 19:20, 20:4.

The Lamb:

Only Revelation can give us these bold insights of the Lamb:

1- They have washed their robes and made them white in the blood of the Lamb. (Rev.7:14).
Make the robs white in the blood?... yes, it is!... the only way!... for Christians and for Abraham and Moses, who are in Heaven as Jesus tells us in Lk.13:28 and Mt.8:11... because the redemption of the Lamb is retroactive, up to Adam and Eve.

2- For the Lamb at the center of the throne will be their shepherd (Rev.7:17):
A lamb who is a shepherd?... yes, he is for all eternity.... and He is now your shepherd and mine... what a good shepherd we have right now: A lamb!... The Lamb!... God is my shepherd, nothing I shall want... (Psalm 23).
