His death he paid the full penalty for 'the sins of the world', once and for all

Mark 15:29-41
Those who passed by hurled(投) insults(侮辱) at him, shaking their heads and saying, "So You who are going to destroy the temple and build it in three days, come down from the cross and save yourself!"
Those crucified with him also heaped insults on him.
At three in the after noon Jesus cried out in a loud voice, "Eloi, Eloi, lema sabachthani?" which means "My God, my God, why have you forsaken me? With a loud cry, Jesus breathed his last.
The curtain of the temple was torn in two from tip to bottom, And when the centurion, who stood there in front of Jesus, saw how he died, he said, "Surely this man was the Son of God!"
His suffering was 'for us and for out salvation'. By his death he paid the full penalty for 'the sins of the world', once and for all. In Jesus' own words, recorded in the Gospel accounts of the Last supper, his body was broken and his blood was shed to make a ' new covenant' between human beings and God. by his death he reconciled us to God, making possible the free gift of eternal life.
Why?
Before this day people welcome Jesus enter Jerusalem, but today people passed by hurled insults at him, how different those people to look Jesus. Same as people now what their perspective is to Jesus.
Jesus was alone so he cried out "My God, why have you forsaken me?"
No come to Jesus asked for miracle or healing but for honor his name and follow Jesus, for Jesus is my salvation and my hope. His death paid the full penalty for the sins of the world.
Jesus sacrificed himself for our sins once and for all. Jesus make a new covenant between us and the Lord.
How?
Remember Jesus death for our sins and forgive me fully, once and for all
