He taught them (and us) that it is in constant communication with the Father in prayer that we can develop our faith. And communication with Him will always be clear and invigorating if we bear no ill will against anyone, sustained by a forgiving heart. His message was: it would be better for a man not to exist at all if he was not fruitful and had nothing to offer in his life. In the same way, one must be willing to give up his life to fight for the truth and the principle of his faith.
Grant me, dear God, a heart full of faith in Your love; with courage to drive out of my life what is evil and unjust; with enthusiasm to be fruitful in spreading the Good News of Christ; and forgiveness, to be worthy of His great sacrifice. Amen.
