Quick recap:
1st Reading - Ezekial - turn from wickedness to what is right and just
Psalm 25 - Remember your mercies, O Lord.
Epistle - Philippians 2 - regard others as more important than yourself (humility)
Gospel - Matthew 21 - Will you change your mind and embrace God's mercy, or will you be stubborn? Today's Gospel outlines the story of a man and his 2 sons. He asks them both to go work in the vineyard. The fist son says no, but then changes his mind and goes out. The second son says yes, but did not go. Thus, on the surface, the second son appears to be more obedient, while in reality, the first son is the one who actually obeyed his father.
