Yet it was the Lord's will to crush him and cause him to suffer,
and though the Lord makes his life an offering for sin,
he will see his offspring and prolong his days,
and the will of the Lord will prosper in his hand. (Isaiah 53:10 NIV)
Jesus Christ did this to set an example for us. He showed us mere mortals, how we can walk through our insignificant hardships just because Jesus Christ, according to the will of Our Father, walked through the worst, just for us. He, Jesus Christ, has borne all and even worse.for us. "Asking three times".....for me this means if we pray hard enough, we will be able to overcome anything through Our Lord...since nothing is possible for us......in our own strength......but everything is possible through God.
