What is the seal of God?

In the near future the great disaster is to come upon the whole world. How can we escape such a great disaster then? The Bible warns us that we must have God's seal to stay safe from the last plague.
First, let's find out when God begins to put a seal on His elect.

Rev 7:1 After this [the World War II, Rev 6:12] I saw four angels standing at the four corners of the earth, holding back the four winds of the earth to prevent any wind from blowing on the land or on the sea or on any tree.

God will start putting a seal after the World War Two and finish it before the four winds of the earth blow on the whole world.

Where does God's work of putting a seal start?

Rev 7:2 I saw another angel coming up from the east, having the seal of the living God.

God will begin to put a seal on His elect from the east.

What is the seal of God? Let's find out through the Bible.

Jn 6:27 On him [Jesus] God the Father has placed his seal of approval.

God has put His seal on Jesus. Therefore, Jesus is God's seal itself. Now let's find out how we can have God's seal through Jesus.

Jn 6:56 Whoever eats my flesh and drinks my blood remains in me [Jesus], and I in him.

Jesus, God's seal, will stay inside us once we have His flesh and blood. We can survive the last plague at the Judgment day. How can we have Jesus' flesh and blood, God's seal?

Mt 26:17-28 Take and eat; this is my body … Drink from it, all of you. This is my blood of the covenant.

We can have God's seal, Jesus' flesh and blood, by keeping the Passover. Only the Passover, God's seal, can save us from the great disaster on the last day.

Let's confirm that we will need God's seal on the last day through the Exodus in the time of Moses.

Ex 12:1-13 When I see the blood, I will pass over you. No destructive plague will touch you.

In the time of Moses, the Israelites were saved from the destructive plague when they kept the Passover. It serves as a shadow, letting us know that no destructive plague will touch us at the last day when we keep the Passover. Now let's find a couple of examples that the Israelites got saved from the destructive plague by celebrating the Passover.

2 Ch 30:1 Hezekiah sent word to all Israel … celebrate the Passover to the LORD.
:10 The people scorned and ridiculed them.

In the time of King Hezekiah, Israel didn't keep the Passover and Judah celebrated the Passover. Let's find out what happened to Israel and then Judah.

2 Ki 18:9-10 Samaria was captured (by the Assyrians) in Hezekiah's sixth year.

Israel was totally destroyed because it did not keep the Passover.

2 Ki 19:30-35 The angel of the LORD went out and put to death a hundred and eighty-five thousand men in the Assyrian camp.

On the contrary, nothing happened to Judah from the Assyrian attack with God's protection because they had celebrated the Passover, God's seal.

These two different cases were written to teach us how important the Passover is for our salvation at the last day.

Ro 15:4 Everything that was written in the past was written to teach us.

The Israelites escaped the ten plagues in Egypt by keeping the Passover. In the time of King Hezekiah, God protected only Judah which celebrated the Passover. These examples show us that the Passover is surely God's seal. Only the Passover will save us from the coming disaster at the last day. Keep the Passover, and you will have God's seal and be saved. God bless you.
