I know this was written a long time ago, but for those who may be reading it today. I don't think you can be a Christian and not do good works. If you only see good works as what you do in ministry, you are greatly limiting what Paul meant. Consider these Scriptures:
Romans 12:1, I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. We are Christians every single day. We are to live for Christ even in the smallest things we do, like thinking and talking. Consider another Scripture:
Colossians 3:17 And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. There is really no such thing as a Christian not living for God in some way, even if parts of your life are not yet transformed.
