“Therefore I will divide him a portion with the many,
and he shall divide the spoil with the strong,
because he poured out his soul to death
and was numbered with the transgressors;
yet he bore the sin of many,
and makes intercession for the transgressors.” -Isaiah 53.12
Isaiah 53 closes with one last reminder of why Jesus came: to “[bear] the sin of many” and to “[make] intercession for the transgressors.”
The child was promised to be king, and after doing what no other man could do, he was exalted as such by his Father in heaven (Acts 2.32-33, Ephesians 1.20-23). The child given gifts by the Magi, is now given gifts by God, and in his majesty he has decided to share that gift, that royal inheritance, with those who are called by his name (Romans 8.12-17, Galatians 3.26, 1 Peter 1.3-5).
This is the good news. This is the Gospel. This is the reason for the season.
