Three crosses. Only on need be mentioned - that of Jesus. Why the other two? Because you are on one of the other crosses. The question is, which one are you on? Accept or reject.
Carrying his own cross, he went out to the place of the Skull (which in Aramaic is called Golgotha). Here they crucified him, and with him two others—one on each side and Jesus in the middle.
One of the criminals who hung there hurled insults at him: “Aren’t you the Christ? Save yourself and us!”
But the other criminal rebuked him. “Don’t you fear God,” he said, “since you are under the same sentence? We are punished justly, for we are getting what our deeds deserve. But this man has done nothing wrong.”
Then he said, “Jesus, remember me when you come into your kingdom.”
Jesus answered him, “I tell you the truth, today you will be with me in paradise.”
