“They have kept themselves as pure as virgins, following the Lamb wherever he goes. They have been purchased from among the people on the earth as a special offering to God and to the Lamb. They have told no lies; they are without blame.” Revelation 14:4-5
The worship of the Antichrist during the tribulation will be so vile and perverted. In the midst of that darkness the 144,000 will shine forth like a beacon of purity. Despite the rampant sexual sin that surrounds them, they will not be defiled. These are the ones who follow the Lamb wherever He goes: These 144,000 are of Jewish heritage (Revelation 7:4-8). Yet they are also clearly believers in Jesus, otherwise they would not stand with the Lamb, follow the Lamb wherever He goes, and could not be without fault before the throne of God. They will be completely loyal to the Lamb no matter what the cost. These are the type of followers that Jesus seeks. “Then Jesus said to his disciples, “If any of you wants to be my follower, you must give up your own way, take up your cross, and follow me.” (Matthew 16:24) John explains that the 144,000 have been purchased from among men. Each of the vast multitudes saved during the Tribulation will be saved in exactly the same manner as anyone today: by grace, through a personal faith in Jesus Christ unto salvation. Even though the rapture of the church ends God’s dealings with the church as such on the earth, it certainly does not change the way people come to salvation or become part of the larger family of God, which includes all the redeemed, before and after the church.
The 144,000 will not propagate Satan’s lies, but will speak God’s truth. “Instead, we will speak the truth in love, growing in every way more and more like Christ, who is the head of his body, the church.” (Ephesians 4:15) Knowing the importance of accurately handling the word of truth they will be diligent in handling God’s Word. “Work hard so you can present yourself to God and receive his approval. Be a good worker, one who does not need to be ashamed and who correctly explains the word of truth.” (2 Timothy 2:15) The 144,000 will trust God’s power and lead lives characterized by purity, the 144,000 will be blameless. That does not mean that they are sinless, but they will be above reproach, leading Godly lives before all who see them.
