The bloody cross was the way a lost humanity could be reunited with a holy God.Jesus was scourged with a whip because our sins required punishment. He was executed upon a cross because our sins required atonement. He – the Son of God – was willing to provide it.
In doing so, he made a way for us to be restored to God.
…Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— children born not of natural descent, nor of human decision or a husband’s will, but born of God. (John 1:11-13)
Isaiah 53:10-13 completes the prophetic passage that refers to Jesus: mentioning his death, resurrection and the relationship that is offered.
10 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.
11 After he has suffered,
he will see the light of life and be satisfied;
by his knowledge my righteous servant will justify many,
and he will bear their iniquities.
12 Therefore I will give him a portion among the great,
and he will divide the spoils with the strong,
because he poured out his life unto death,
and was numbered with the transgressors.
For he bore the sin of many,
and made intercession for the transgressors.
