Today we live in 2017 AD. But 1800 years ago the A.D. stood for “Anno Diocletiani” which means “the year of Diocletian,” a ruthless, anti-Christian Roman emperor. In 525 AD, a monk named Dionysius proposed changing the A.D. to “Anno Domini” which means “the year of our Lord,” referring to the Advent of Jesus Christ. Then to mark the dates of the calendar before Christ’s birth properly, the “B.C.” (before Christ) period was introduced.
But BC/AD is just a dating system. There is no such thing as “BC”—there has never been a time before Christ! He has always been! Throughout what we now refer to as the Old Testament (or the BC period), Jesus is constantly revealing Himself through little hints here and there, but when He comes to earth as a Man, all the hints become a bright, blazing, unmistakable Truth!
Just like Dionysius came up with a new dating system based on the Advent of Jesus, the Israelites had a new starting point marked by the Passover (see Exodus 12:1-7). Everything from this point backward is reset and dates are now counted forward from this moment. Before this time they were slaves in Egypt; after this time they were free and called God’s special people.
The “BC” Passover had three important components:
- A perfect lamb without any defect (Exodus 12:5)
- The lamb is slaughtered at twilight (v. 6)
- The blood is applied to the door (v. 7)
When Jesus came to Earth, He showed how He was all three of those elements. In the “AD” Jesus is—
In both BC and AD God declares the same message: “When I see the blood, I will pass over you.” The blood seals the deal and brings God’s forgiveness of sins, and His blessings on the life that is now completely His.
The word remember appears frequently in the BC, as in “remember what God did for you.” In the AD remember appears at a pivotal time—when Jesus shared His last supper with His followers, He told them that Communion would be a time for them to remember all that Jesus did for us as the Perfect Lamb, whose Blood is applied to the Door of our heart, so that God’s judgment could pass over us.
Do you have a Passover date? A time when the BC became AD in your life? If so, good! Keep remembering that, and don’t ever go back to being a citizen of anything but God’s Kingdom.
If not, today can be the first day of a new era for you. By faith you can apply the Blood of the Perfect Lamb to the Door of your heart, and you will no longer be a slave of “Egypt” (a picture of being utterly trapped and unable to help yourself), but a citizen of Heaven! All it takes is for you to believe that Christ’s blood purchased your freedom, so you can ask God the Father to forgive you of all your BC past, and then you can live forever in the AD with Jesus as your Savior and Master!
