Modern Christians are faced with similar difficulty. Young people are told that to be accepted they must go along with the crowd - drugs, sex, alcohol. To refuse is to be excluded. The list of problems could go on and on. But compromise WAS not and IS not what the Lord can tolerate.
Compromise is unacceptable.
What a sad thing for Jesus to have to say to a church that appeared to be doing so well. But it is a message that has borne repeating through the centuries. It bore repeating a thousand years ago when the church had become so politicized that, in the name of Christ, we became aligned with princes and kings in their international land-grabs. It bore repeating 500 years ago when the leaders of the church became so concerned with their own personal power and prosperity that a reformation was set off. It bore repeating 70 years ago when the church in Nazi Germany allowed itself to be used to further the demonic aims of a mad man.
