A fan will try and accept the invitation of Christ to follow, but they don’t want to say no to themselves. In Luke 9:23 Jesus makes it clear that if we are going to follow him, a casual, no-strings attached arrangement isn’t a possibility:
If anyone would come after me, he must deny himself…
You can’t “come after” Jesus without denying yourself.
