Luke 17 (The prodigal son)
27) And he said unto him, Thy brother is come. And Thy father has killed the fatted calf, because he hath received him safe and sound. 28) And he was angry, and would not go in: there-fore
came his father out, and intreated him. 29) And he answering said to his father, Lo, these many years do I serve thee, neither transgressed I at any time thy commandment: and yet thou never gavest me a kid, that I might make merry with my friends: 30) But as soon as this thy son was come, which had devoured thy living with harlots, thou hast killed for him the fatted calf. 31) And he said unto him, Son, thou art ever with me, and all that I have is thine. 32) It was meet that we should make merry, and be glad: for this thy brother was dead, and is alive again; and was lost, and is found.
The Father of the prodigal son was so overjoyed to have his son back with him that he threw a feast fit for a king, and absolved him of any dishonour that he had brought on the family.
In a like manner, The blood of Jesus Christ Atones for every sin ever committed by every human being who has ever lived.
This is the greatest gift that God has given to mankind. Through Him all those who are dead can be made alive, and all those who are lost can be found.
