I just read the following quote from St. Teresa of Avila which is consistent with what I’ve heard of her as someone who is quick witted and spoke her mind. In the passage this quote comes from she is saying that we should approach God in prayer with humility and that we shouldn’t be seeking “consolation”, which is the nice feeling we sometimes feel in prayer. She goes on to say,

Although if some consolation is felt, it shouldn’t cause the disturbance and pain it does to some persons who think that if they aren’t always working with the intellect and striving for devotion all is lost - as though so great a blessing could be merited by their labor. I don’t say that they shouldn’t strive carefully to remain in God’s presence, but that if they can’t even get a good thought, as I’ve mentioned elsewhere, they shouldn’t kill themselves. We are useless servants, what do we think we can do?

I think it is important to be serious about our walk with God, but not take ourselves too seriously. We need to do the best we can, and then not be upset when we stumble and fall, and even our best is not very good. We must remember we are useless servants so that we don’t think too much of ourselves in our victories, or go into despair in our failures.
