Shepherds are supposed to protect their flocks and insure for their well-being. The image of the shepherd was often used in the Old Testament for religious leaders and kings, but often in a negative sense. Ezekiel lamented how much of Israel's shepherds had let her down, for they were wicked and corrupt.
In the prophecy, God promised to take on the job Himself - God would be the shepherd of the nation and its people. Jesus, the fulfilment of that promise, is constantly at work, overcoming all those powers that opposed God - even unto death - to restore the entire world and its people to God the Father. The job is not yet finished, and we are called to take part in this work.
In Matthew's final judgement scene, those welcomed into the kingdom were not aware of having done anything special, and the actions for which they were praised were not religious in nature. They saw human suffering and need and responded with practical compassion. This is the core of true religion, and anyone can practice it.
Those who were sent away were rejected not for what they had done, but for what they had NOT done. They did not respond to human suffering but were concerned only with themselves.
The opposite of love is not hate but indifference. Each day, let us practice God's practical religion - kindness and compassion - we cannot go wrong.
Lord, may I always respond to those in need.
