But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God... Hebrews 10:12

The Message Of The Cross.
Christ no longer needs to be "On" the cross anymore as it has been fulfilled. One sacrifice, one time, it is done.
The cross is empty now and the empty cross reminds us that Jesus is in Heaven.
The empty cross reminds us of His sacrifice and that He is no longer there anymore but is at the right hand of God!
A single sacrifice, one time, for sins.

Jesus, the pure and righteous Son of God, came to take our unrighteouness on Himself, including our punishment.

Thank You Jesus! Amen!
