Who Speaks of Sacrifice and Sinless Living?

Psalm 49 (50) from today's Divine Office: 'Whoever offers up a sacrifice of praise gives me true honour; whoever follows a sinless path in life will be shown the salvation of God.' What sacrifice of praise could this be? Our Lord is our sacrifice, and through Him, our lives can be one of daily praise to the Almighty Father. St. Josemaria Escriva taught more than anything that our daily work sanctifies us, offered up to God through our Lord. Our daily work must be dispensed worthily, like the first fruits of Abel. Living sinlessly with simple joy and working in a worthy manner, we also hope to move people to ponder where it all comes from. God willing, we may get an opening to tell them, and they may connect our behavior with, as the blessed saint said, reading "the life of Jesus Christ."
