I think the main reason people become self-righteous is that their focus is on themselves.
The word itself tells us, SELF-righteousness.
To some extent, all people have a certain level of self-righteousness.
That’s just how human nature works.
We are geared toward thinking of ourselves to the point that we get an illusion of grandeur.
We sadly believe that we are better than anyone else.
This is where self-righteousness starts.
When we do something good, we have this mental notepad where we write all our good works.
We think that we are better than anyone because we think that we have done a lot of good things.
We somehow manage to fool ourselves that God needs us because we are good when in reality, IT IS US who need God.
Now, that’s self-righteousness.
If you want to get a more in-depth answer, please read my mind-opening blog, “10 DEADLIEST Signs of Self-Righteousness You Probably Don’t Know.”
We need to realize that our righteousness is nothing compared to the righteousness of God.
Isaiah 54:6 even tells us that our righteousness is like filthy rugs.
This means that even the best good things that we do in this life, if we really think about it, are still NOTHING compared to the righteousness of God.
Now, here’s something you need to realize.
No matter what good we do, we are still sinners.
No amount of good things that we do could ever erase the penalty of sin we have committed.
That’s why we need a Savior.
The moment we commit sin, the penalty of death is already hanging on our necks.
And you know what the good news is?
It is that Yahshua or Jesus Christ died for us.
Instead of us who will die for our sins, it is Christ who died on our place.
He already paid for our sins.
That’s why we can never earn our salvation and it is only through the sacrifice of Yahshua that we are given the chance to be part of God’s Kingdom.
Yes, the cause of self-righteousness is simply because we think we are better than others and God – that our righteousness earned us our salvation.
That’s never the case.
We need to realize that it is God’s righteousness that has given us life and the chance to be part of His Kingdom.
Always remember that you do good works not to direct people’s attention to you, but to direct their attention to our Heavenly Father.
As Matthew 5:16 tells us:
Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
I hope you learned something from my answer.
