Generally speaking, we may like to think we are quite good persons.
We may not be that good all the time but at least we can say that we are not that bad.
So we tend to measure our goodness by what we think is bad.
But even if we measure our goodness by the moral standards of the 10 Commandments, can we say that we are good enough?
In the 1st reading, God instructed Moses to say this to the people: Be holy, for I the Lord your God, am holy.
No one is truly good but God alone, and His goodness flows from His holiness.
And in whatever good that we do, it should radiate the holiness of God.
It may be feeding the hungry, giving drink to the thirsty, welcoming the stranger, clothing the naked or visiting the sick or those in prison, like the parable in the gospel.
Or it may just be doing a small and little thing with great love.
We acknowledge that we are sinners and that we are not that good.
But doing everything with love makes us good enough for God, for in His holiness, He does everything with great love.
