I like this passage from Thomas Merton about Lent. It makes me think that Merton would approve of my Lenten resolution, to give up self-loathing. He writes:
The purpose of Lent is not only expiation, to satisfy the divine justice, but above all a preparation to rejoice in His love. And this preparation consists in receiving the gift of His mercy–a gift which we receive insofar as we open our hearts to it, casting out what cannot remain in the same room with mercy.
Now one of the things we must cast out first of all is fear. Fear narrows the little entrance to our heart. It shrinks up our capacity to love. It freezes up our power to give ourselves. If we were terrified of God as an inexorable judge, we would not confidently await His mercy, or approach Him trustfully in prayer. Our peace and our joy in Lent are a guarantee of grace.
