Here are some quotes on Faith by Saints:

1.If you believe what you like in the gospels, and reject what you don't like, it is not the gospel you believe, but yourself.
--Saint Augustine

2,“Be faithful in small things because it is in them that your strength lies.”
--Blessed Mother Teresa of Calcutta

3.“One life is all we have and we live it as we believe in living it. But to sacrifice what you are and to live without belief, that is a fate more terrible than dying.”
--St. Joan of Arc

4.Where there is hatred, let me sow love. Where there is injury, pardon. Where there is doubt, faith.
--Saint Francis Assisi
