24 You blind guides, who strain out a gnat and swallow a camel! Matthew 23:24 (NASB)
A huge trap that Christians can fall into is self-righteousness. It is a form of idolatry and that always causes spiritual blindness (Romans 1:24-25). Self-righteousness puts all effort towards godliness in the wrong place. It creates a form of piety that is all about outward appearances while putting little or no priority on matters of the heart. It is all about being concerned about appearances and what others think rather than being totally committed to abiding in Christ from within first. The self-righteous are consciously holy. However, that is not what we are called to be. Christians must be consciously repentant and unconsciously holy. The difference is huge for these are totally opposite walks.
