~St. John Chrysostom, Commentary on Galatians
It's not just big sins that bring us down, little ones slowly eat away at our souls. Like neglecting an illness, the spirit gets sicker and sicker.
So, how are we healed? How are we delivered? Our recovery is also a gradual process. We don't need to make BIG sacrifices to be holy. St. Therese of Lisieux (Ta-rez of Lee-zyoo) wanted to be a martyr and do great things for God, but when she couldn't she discovered the "Little Way'. By making small sacrifices and little act for Christ she became a kind of martyr.
Of course, we also have the Church, which is a spiritual hospital where we are healed through the Sacraments of Confession and the Eucharist. We also have each other for fellowship, intercession, help and encouragement.
