The crucifixion of Jesus was the result of His mission being interrupted. When Jesus started there were no talks about crucifixion (see Matthew 4:23-24) it is only when he realized that he could not do what he wanted that he started to speak about his path of suffering. Anyone who rejoices in the death of Jesus may not understand that God is our parent. No individual, worthy of that title, would ever rejoice in the death of their offspring.
Wikipedia says: "Good Friday (from the senses pious, holy of the word "good"), is a religious holiday observed primarily by Christians commemorating the crucifixion of Jesus Christ and his death at Calvary."
GotQuestions.org respond to the question, "Why is Good Friday referred to as good?": What the Jewish authorities and Romans did to Jesus was definitely not good (see Matthew chapters 26-27). However, the results of Christ’s death are very good! Romans 5:8, “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” First Peter 3:18 tells us, “For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive by the Spirit.
Today we have much to learn, and we must not believe blindly. We must know the hidden truth behind the Bible. Jesus was crucified, not by his own will, but by the will of others. Jesus Christ was killed because humankind would not have faith in him as Messiah. Jesus Christ was murdered. People living at the time of Jesus Christ made a terrible mistake. According to Jesus, John the Baptist was Elijah. But alas, John himself denied that he was Elijah when he was asked! His denial made Jesus seem to be a liar. This was such a grave situation. The crucifixion of Jesus was a result of human faithlessness. If death on the cross had been fulfillment of God's will, Jesus would certainly have prayed instead, "Father, I am honored to die on the cross for your will."
The prayer of Jesus at the garden of Gethsemane did not come from his fear of death or suffering. Jesus would have been willing and ready to die a thousand times over if that could have achieved the will of God. He agonized with God together in the garden, and he made one final plea to God, because he knew his death would only cause the prolongation of the dispensation.
