"For such men are false apostles, deceitful workmen, masquerading as apostles of Christ. And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve." -- 2 Corinthians 11:13-15
It's that time of year when children and even adults "masquerade" as someone other than themselves. They dress in costumes for fun and entertainment, but there are those who regularly change their identity for evil purposes. Some wear masks to rob banks and others change names and appearances to deceive people out of money. The "masquerade" eventually leads to their condemnation.
In the spiritual life there are many who seek to lead others astray for personal gain. They talk the talk and appear to be true believers, but in fact they are simply false apostles. They preach and teach another Jesus than the Lord of the Bible. Paul wrote with great concern for his spiritual children, that they would not be deceived like Eve had been in the garden. Remember, if someone's righteousness is only a "masquerade", it will only lead to condemnation.
Costume parties may be fun for the moment, but we eventually need to take off our masks and embrace the truth. Be careful of those who are not the real deal and strive to lead you down the wrong path. Be discerning when listening to the teaching of others and settle for nothing short of the God of the Bible. Any other God is a "masquerade" and will only lead to condemnation.
