It is Jesus himself who is bringing the grace through the sacraments. He is the one who instituted the sacraments. All the sacraments flow from Jesus. He is the source. Without him, the sacraments would be empty symbols and rituals.
But, because Jesus is there, they have power.
In every sacrament, Jesus is waiting for you. Living waters pour out from his heart for you. Come to the sacraments with expectant faith. Jesus is waiting to release powerful graces into your life when you do.
