I can’t do better than a B.C. comic by Johnny Hart, which I can’t reproduce here.

• Cave man #1: I hate the term “Good Friday.”
• Cave man #2: Why?
• Cave man #1: My Lord was hanged on a tree that day.
• Cave man #2: If YOU were going to be hanged on that day, and he volunteered to take your place, how would you feel?
• Cave man #1: Good
• Cave man #2: Have a nice day.

He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed. (1 Peter 2.24, ESV)

God shows his love for us in that while we were still sinners, Christ died for us. (Romans 5.8, ESV)
