A NUGGET OF TRUTH.
THE SEALING OF GOD'S PEOPLE IS ONGOING, WHILE THE ANGELS HOLD BACK THE WINDS OF STRIFE.

REV 7:1 Says there are four Angels holding the four winds of the Earth and these winds are symbols of strife, war, destruction and trouble [ Prov 1:27, Jer 23:19].

God has powers working on this world to hold back the Evil forces, so that His people have a chance to get ready for His coming.

REV 7:3 Says there is another Angel ascending from the East having the seal of the living God, saying Hurt neither the earth, sea nor trees till we have sealed the servants of God in their foreheads.
Earth= Where there are just few people ( Jer 51:43).
Sea= Areas with lots of people ( Rev 17:15).
Trees= Means government or rulers ( Remember Nebuchadnezzar's dream where a great tree was used to mean his rule in Babylon ( Daniel 4).

If the Angels were not Holding back the " winds" Satan would destroy the whole Earth.

FOREHEAD represents mind( Rom 7:25, Eze 3:8,9). This is where the frontal lobe of your brain is located where decision making process takes place, reasoning, judgement and character, now this means that God's people will chose with their minds to believe and obey God.

In EZEKIEL 9 we see a man with writers inkhorn placing a mark on those that " sigh and cry" because of all the wicked things people are doing and ignoring God's Holy law.
God is seeking to seal something up within the characters of His servants before he allows great tribulation to come upon this Earth. it is not any seal or Mark that can be seen but a settling into the TRUTH both INTELLECTUALLY and SPIRITUALLY so that they cannot be moved.

A seal is like a stamp of ownership. A seal authenticates a document, a seal attest to the Authority of that document and it is a test to the one who wrote the document.
A legal seal usually have the NAME of the sealer, the TITTLE of the sealer and the TERRITORY of the sealer.
The 7th day SABBATH the 4th Commandment is the seal of GOD'S 10 COMMANDMENTS LAW( Exodus 20:8-11).

It is the only place where it tells;
1. God's name( the Lord thy God)
2. His Tittle ( He is the creator).
3. His territory ( Heaven and Earth).
The sealed people of God will keep His true SABBATH, The Sabbath will represent in the last days of Earth history a settling into the Truth, so that we cannot be moved.[ see Ezekiel 20:12, 20 & Exodus 31:13].

Friends, we can see clearly from Scripture that it is within the Sabbath commandment that we find the SEAL OF THE LIVING GOD. It is within the Sabbath Commandment that we find the SIGNATURE of the Omnipotent. Thus, from this background, it is clearly evident that the SEVENTH-DAY SABBATH IS THE SEAL OF THE LIVING GOD.

Beloved, the Sabbath is the sign of God’s ultimate relationship with His people. Right after the creation of our world, the Lord filled the Sabbath hours with abundant blessings, and gave it as a precious gift to the human race (Mark 2:27).(See Genesis 2:1-3)
Friends, thus right after creation, the Sabbath has been the sign of God's ultimate relationship with His children. The Sabbath has been the means through which the Lord sanctifies His people.

Beloved, the keeping of God's commandments, particularly the Sabbath, is what will distinguish God's end time people from the rest of the world. The final battle in the great controversy between Christ and Satan will still be over worship, and the Seal of God's Creatorship (which is the Sabbath) will be set in contention to the Mark of the beast( Sunday). The world will be brought to make a choice, and none would remain neutral.
