Jesus uttered his last words as the son of man when He hung on the cross. “It is finished.” He said. Then, the Bible says, “He gave up His spirit.”
What did He finish? When Jesus was praying to The Father in John 17, Jesus said, “I have finished the work you have given me to do.”
The “work” Jesus came to do was,
1) to “seek and save that which is lost”
For the Son of Man came to seek and to save that which is lost.” Luke 19:10
2) Jesus paid our sin debt. He is our forgiveness for all the sins we ever committed, are committing and will ever commit. That debt was paid in full on the cross.
He himself bore our sins” in his body on the cross, so that we might die to sins and live for righteousness; “by his wounds you have been healed.”
3) The third work Jesus finished on the cross gave man a way to reconcile him to God and re-establish the relationship between God and us, His children.
And this is the testimony: God has given us eternal life, and this life is in his Son.Whoever has the Son has life; whoever does not have the Son of God does not have life. 1 John 5:9
