It Is Finished!

What did Jesus say after drinking the sour wine?
"It is finished!" (John 19:30, see Sour Wine)

After how many hours on the cross did Jesus say, "It is finished"?
After being nailed to the cross at 9 AM, which is the "third hour" from sunrise, deemed to be at 6 AM - "Now it was the third hour, and they crucified Him" (Mark 15:25) - Jesus died at 3 PM: 44 Now it was about the sixth hour, and there was darkness over all the earth until the ninth hour. 45 Then the sun was darkened, and the veil of the temple was torn in the middle. 46 And when Jesus had cried out with a loud voice, He said, “Father, ‘into Your hands I commit My spirit.’” Having said this, He breathed His last" (Luke 23:44-46). So Jesus said, "It is finished!" after six hours on the cross.

What happened for three hours before Jesus said, "It is finished"?
"Now it was about the sixth hour, and there was darkness over all the earth until the ninth hour" (Luke 23:44).

Was that an eclipse?
It couldn't have been, since the Passover is during full moon. The "darkness" may have had something to do with the sins from across the world and time being poured into Jesus (see John 18).

So what was "finished"?
For two thousand years since Jesus passed through the blood of sheep, goat, cow, dove and pigeon to promise Abraham that He will die to pay for the sins of Abraham and His descendants (see Genesis 15), the Jews had been sacrificing those five animals. After the temple was built in Jerusalem, those five animals were sacrificed daily, from 9 AM, which coincides with when Jesus was nailed to the cross, until 3 PM, when Jesus died on the cross, not because they paid for the sins of the people - "For it is not possible that the blood of bulls and goats could take away sins" (Hebrews 10:4) - but to acknowledge God's promise to pay the penalty for their sins. On this particular day, when the shofar - a ram's horn - was blown from the temple at 3 PM to sound the day's last sacrifice, Jesus cried out, "It is finished!" He had kept His promise and paid the penalty for sins, ripped away Satan's grip on humanity, saved countless souls, and obeyed the Father. And when the priest's knife sliced through the throat of the last lamb sacrificed, Jesus "cried out with a loud voice" (Luke 23:46). When the dying lamb's head slumped onto the altar in the temple, Jesus, "bowing His head" (John 19:30), whispered through His dying breath, "Father, 'into Your hands I commit My spirit.'" Having said this, He breathed His last (Luke 23:46).
