I received an email this afternoon from a person who was upset about eternal security - he disagreed with another's viewpoint that one could lose their salvation.
I can understand his frustration, this does seem to be a key issue - and that debate has raged for over 500 years. It's important, but I'm not sure I would fight over it. There are more similarities to the two sides than one would initially think - and they can meet over how one should reach out to someone who has made a profession of faith, but does not follow the Lord over an extended period of time (deal with them as an unbeliever first).
What would I fight over, stand up for, even die for? I would "fight" for Christ's person and work - particularly for salvation by faith. I would fight for our freedom to worship - not necessarily in a church building or formal way - but together with other believers, even "underground". I would fight for scripture being inspired by God, inerrant. I would fight for our "right" to share our faith - or I would at least go ahead and share anyway. Many of the Evangelical Free doctrines are basic enough to "fight" for.
I doubt that I would fight for one particular position on the Lord's coming.
How about you?
