Our sin can only be washed by the bloood of Jesusu shed at calvary. The physical pain the devil inflicted  on Jesus was in an effort to make Jesus sin and denounce His father. IF Jesus had sinned in any way the devil would have won, BUT Christ's death and suffering had been prophesied long time ago (Isaiah 53) and so had to happen. Jesus was the lamb of God who takes away the sin of the world. REmember how Adam and eve after sinning hid from God because they were naked? Theyhad sewn leaeves to cover themselves? How long would the leaves last before drying up? So God in His abundant love and mercy covered them with the skin of an animal? which animal do you think God killed so that Adam and eves nakedness would be covered? God still coveres our nakedness if we believe in Jesus  sacrifice on the cross. John the baptist at the Jordan points to Jesus and tells people to behold the Lamb of God who takes away the sins of the world. Back again to Abraham and Isaac his only son. God asks him to sacrifice his son and off he goes...and instead of Isaac dying what do we see, a lamb to die in the  place of Issac.  

So without Jesus death on calvary and shdding of His blood we would be lost foreve. The Devil inflicted so much pain on our Lod, like he continues to do today. Jesus was both man and God...His goal was calvary and only tere would he redeem man not any other death. We must keep our eyes on jesus and know that there is no other way we can have white garments unless washed in His calvary's blood. Spiritual separation from God was as a result of our sin
