Crucifixion of Jesus

Jesus is nailed to a cross at Golgotha.

Question 1: The first words of Jesus from the cross focused on the forgiveness of His persecutors. What, if anything, does this teach us about dealing with those who persecute us?

Question 2: How would you explain the necessity of the crucifixion of Jesus to someone who showed interest in understanding it?

Question 3: The soldiers were more interested in the things of Jesus rather than Jesus himself. How do people display a similar attitude today?
