A different penance
Not long ago I went to confession to a priest who doesn't know me. As a penance he told me to say every time I loose heart: "Heart of Jesus, I trust in You." What great goodness has he done to me. This positive thought helps me remember that I am not alone in hard times.
God's providence works on a daily basis. At times I try to carry the burden not of one day but of many. I know that he provides to those who trust in Him and that he will provide me what I need. But at times I live as if I forget this.
