During the stressful and uncertain moments of Holy Thursday, Jesus tells his disciples to trust in God and in Him.  This is the solution to having a troubled heart: a heart dominated by fear, worry and anxiety.  Our trust in God involves trusting in his Providence.  Providence is God's governance of the world and his guiding it to a good end.  Four key principles of our faith reveal to us that it is impossible to trust in God's Providence too much.
