The true worth of what a Christian does is determined by the active presence of God's grace in him and his deeds. In a Christian's heart, therefore, peace is inseparable from joy.... When the joy that is in a Christian heart is poured out on others, it gives them hope and optimism; it spurs them to be generous in their daily toil and infects the entire society. My children, only if you have in you this divine grace which is joy and peace, will you be able to do anything useful for others.
--Blessed John Paul II, Address, 10 April 1979
The effect of grace, peace and joy
