Ephesians 4: 30 And grieve not the holy Spirit of God whereby you are sealed unto the day of redemption.
Ephesians 1:3 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ. 13 In whom you also trusted, after that you heard the word of truth, the gospel of your salvation: in whom also after that you believed, you were sealed with that holy Spirit of promise, 14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
It becomes clear that being sealed does not prevent a Christian from dying. It just certifies that he or she belongs to God. Therefore, the 144,000 who will be sealed, are not the only ones who will be saved in God’s kingdom in the last days of earth’s history. In fact, there are many millions who will be saved. One of the sticking points on the subject has to do with where John saw the two groups of saints, for in one instance he sees the 144,000 just before the close of probation.
And then he sees a multitude which no man could number, standing on the sea of glass, together with the 144,000. The two groups are depicted as being in different places in the vision given to John, and furthermore, there is nothing in the vision that suggests that the 144,000 is a figurative number.
Revelation 7:1 And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
May The Lord add His blessing to the study of His word. God bless!
