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.
The self-righteous view their sanctification from what they do through works in order to be worthy. The humble Christian, on the other hand, views his or her sanctification as God’s work in them as they walk in repentance by His grace. Their works are simply acts of obedience while their worth is all wrapped up in who their Saviour is instead of what they have done.
