Ash Wednesday Reflection

Why is it that on Ash Wednesday, we always hear from the Gospel of Matthew about" not performing deeds of righteousness in order that people see them", we then proceed to have the priest make a cross of ashes on our forehead as we then go out into our workplaces, schools, and the public square? Doesn't this seem a paradox? While the gospel is a good reminder not to flaunt our good deeds nor to think we are better than others because we went to mass on a weekday, the truth is we don't wear the ashes as a sign of righteousness but rather as a recognition of our humble nothingness, owing everything to God, The priest usually says"remember that you are dust and to dust you shall return" ... biblically a sign on your forehead is a symbol of ownership, that we belong to God. As we begin this Lenten season of fasting and penance, Let us remember that we can do nothing without God and that He will give us the strength to endure everything.
