Definition: The word "Afterglow" comes from a biblical passage in the book of Revelation, which we refer to as Revelation Chapter 19:20: "In the same place where the firstborn cried out to the Lord, so shall the secondborn cry out to the Lord; the third-born shall rise up and sing praises to Him, and they shall be saved. This is what the Lord has done." The exact translation from King James Bibles is: In the same place where the firstborn cries for God, so shall the secondborn cry for His mercy. The third-born shall raise themselves up and praise the Lord, and the people that are alive and have not died shall be saved. This verse tells us of a period in human history when salvation was possible, but only through faith, as demonstrated by the miracles described in the Bible (such as the birth of Jesus Christ, the resurrection of the dead, etc.). The secondborns who cried out for God would rise up and praise Him. This act of worship is said to be a sign of faith and is seen as a sign that God had already accepted them into His family. The word 'afterglow' in this context refers to the period of time during which the saved people are experiencing joy, peace, and strength from their faith. It could also refer to the spiritual afterlife where they are rejoicing with the Lord. This is a metaphorical meaning of salvation and it's often used in Christian literature for this purpose. The details of how this happens can be described as follows: 1. The firstborns cry out in praise of God, seeking His mercy. 2. Then the secondborns rise up to worship Him and praise Him. 3. This raises their spirits, making them feel closer to God. 4. The third-borns are saved when they acknowledge their faith by rising from the dead and praising God. The afterglow is often seen as a period of time when people experience joy, peace, and strength from their faith, and this period is considered to be a sign of salvation.
