Hi All,
The politics of Handel’s time discussed are interesting but none really answered the OP’s question set forth. The term in the prophesy “And the government shall be upon his shoulder” to me meant that both the Romans and the Jewish leadership of that time would actively oppose him at every opportunity and eventually be responsible for his death. If you follow the Bible you’ll find that this was the ultimate goal of God. Jesus was offered up as an atonement for man’s sins. This provided a path for man’s salvation to all that believed in him.
This is a great work that I believe was written through the inspiration of the Holy Sprit. Handel may not have been a religious man but this wouldn’t have been the first time that God used people to attain his objective whether they were believers or not. If you are familiar with the Bible you will find that God has used such people to attain his objectives more than once.
