How do we put faith into action without crossing the line into fear or sensationalism?

It appears we face a lot of apathy among American Believers, and many Christians don’t seem to be upset about things that we should find upsetting. Romans 12:9 says to “abhor that which is evil” and Ephesians 5:10 says we are to “reprove” the works of darkness. How do we preach the message of putting our faith in action without crossing the line into scare tactics or sensationalism?
