Of the two Greek word groups used to convey the concept of regeneration, the Greek word, "palingenesia," is used only twice throughout the New Testament.

"Palingenesia" is a compound noun from "palin" (which means "again") and "genesis" (which means "birth" or "origin").

1. Carefully observe the passage that the apostle Paul pens to Titus who he is discipling. Paul describes Titus as "my true son in a common faith: Grace and peace from God the Father and Christ Jesus our Savior" (Tit 1:4). What does regeneration do? List as many reasons that you can observe.

But when the kindness of God our Savior and His love for mankind appeared, He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration (palingenesia) and renewing by the Holy Spirit, whom He poured out upon us richly through Jesus Christ our Savior, so that being justified by His grace we would be made heirs according to the hope of eternal life. (Tit 3:4-7, NASB)

2. Carefully observe Matthew's conversation between Peter and Jesus. The disciples just saw Jesus tell a rich young ruler the high cost of following Him. And Jesus said to His disciples, "Truly I say to you, it will be hard for a rich person to enter the kingdom of heaven. And again I say to you, it is easier for a camel to go through the eye of a needle, than for a rich person to enter the kingdom of God." When the disciples heard this, they were very astonished and said, "Then who can be saved?" (Matt 19:23-25, NASB) What do you learn about regeneration?

Then Peter said to Him, "Behold, we have left everything and followed You; what then will there be for us?" And Jesus said to them, "Truly I say to you, that you who have followed Me, in the regeneration (palingenesia) when the Son of Man will sit on His glorious throne, you also shall sit upon twelve thrones, judging the twelve tribes of Israel. And everyone who has left houses or brothers or sisters or father or mother or children or farms for My name's sake, will receive many times as much, and will inherit eternal life. But many who are first will be last; and the last, first. (Matt 19:27-30, NASB)
