I will call last week as "Unity Week" because two sermons on Unity were preached which I will preach on it too for my Homiletics class using Philippians 2: 5-11. I really agree that unity is the evangelistic tool for the non-Christians. Through division, how can the kingdom stands? How people see us as Christian?
Sometimes, I think that when our lives is so comfortable, at peace, we tend to focus on other things than preparing for the coming of the Lord. We should live as though Jesus will be coming on tomorrow. This is what my lecturer said, the view of Eschatology has changed when Jesus seems to delayed his coming.
What I've done is to not let myself in peace or comfort in order not to lose the passion and the intimate dependency to the Lord.
