Repentance

 
In God's Word two Greek words are translated into the one English word "repentance."
One of the Greek words means "change of heart," or "to turn about." The other Greek word means "regret."
Judas Iscariot had "regret," not a "change of heart." "Judas repented himself." Matthew 27:33Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders, (Matthew 27:3). But a complete "change of heart" is indicated in the words of the Lord Jesus in Luke 13:33I tell you, Nay: but, except ye repent, ye shall all likewise perish. (Luke 13:3). He says there, "Expect ye repent, ye shall ALL likewise perish."
