As we grow in the Christian life we face increasing danger of spiritual pride. We know the correct doctrines, the right methods, and the proper do's and don'ts. But we may not see the poverty of our own spiritual character. We may not see our critical and unforgiving spirit, our habit of backbiting, or our tendency to judge others. We may become like the Laodiceans of whom our Lord said, 'You say, I am rich; I have acquired wealth and do not need a thing. But you do not realize that you are wretched, pitiful, poor, blind, and naked' (Revelation 3:17).
