The gospel tells us a beautiful story of mercy (compassion, kindness, gentleness), of how Joseph de Arimathea, a pious and devoted man of the Lord Jesus, was moved by the death of his teacher, and once he died, ordered everything for his burial. At a time when the disciples of Jesus had been dispersed and hidden by persecution, Joseph de Arimathea was not afraid, and like Tobit in the old testament who buried his brothers murdered in Nineveh, gave Jesus a dignified burial, so it is recounted in the Gospel of Saint Matthew:
"As evening approached, there came a rich man from Arimathea, named Joseph, who had himself become a disciple of Jesus. Going to Pilate, he asked for Jesus' body, and Pilate ordered that it be given to him. Joseph took the body, wrapped it in a clean linen cloth, and placed it in his own new tomb that he had cut out of the rock. He rolled a big stone in front of the entrance to the tomb and went away" Matthew 27:57-60.
The narrations about this character in the gospels are very brief, and the evangelist Luke even mentioned that he was a member of the council, an important position at the time. John instead tells us that Joseph of Arimathea was a secret disciple of his teacher Jesus.
The Bible with these stories seeks to show us the backlight, Nicodemus who sought instruction, and Joseph de Arimathea give us an example of what it means to seek beatitude with the heart, that beatitude that Jesus preached, open our hearts and make it available to others:"So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets" Matthew 7:12.
But the Bible also shows us the opposite, to Pontius Pilate who only sought to sustain himself in power and not to do justice, and to Judas Iscariot who sold his teacher for a few coins.
The Kingdom of Heaven shows us the eternal opposition between good and evil
