Today's Gospel reading at Mass came from Mark 9. I urge you to read verses 43-48 which teach us about dealing with sin. It tells us how important it is for us to be holy, for the consequences can indeed be grave. God is merciful, but not to stop sinning is to abuse his mercy. After receiving Communion, I saw that God has given us all, his own Son and all we need to know and do to be saved. What's left to be done is giving ourselves to him. It's now up to us.
