Ques. Who will be caught up when the Lord comes? (1 Thess. 4.)
We see in 2 Thessalonians 1:7-9, 2:10-12 that those who hear "the gospel of the grace of God" and reject it, do not get another chance. Satan has blinded them. They have put away God's precious salvation for the pleasures of sin which were but for a season.
To whom will the gospel be preached after the rapture of the heavenly saints?
The "gospel of the Kingdom," the news that Christ is coming to reign (Psa. 2:10-1210Be wise now therefore, O ye kings: be instructed, ye judges of the earth. 11Serve the Lord with fear, and rejoice with trembling. 12Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him. (Psalm 2:10‑12)), will be preached to Israel (Matt. 10:5-75These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: 6But go rather to the lost sheep of the house of Israel. 7And as ye go, preach, saying, The kingdom of heaven is at hand. (Matthew 10:5‑7)); and to all nations, i.e., Gentiles; and those who receive that gospel, will be Christ's subjects on earth. We find a direct testimony also sent to the worshippers of idols in Revelation 14:6-76And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, 7Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters. (Revelation 14:6‑7).
Such is man, all men, unless through grace they are born again. How easy it is to let present things blind us to the truth.
