from At the Fountain of Elijah
She [St. Teresa of Avila] is aware from her own conversion experience of the need to grow from a solid human basis. Prayer comes from a life of practical love, from detachment and humility. We cannot talk to God if we do not speak lovingly to our neighbour and we need realism, and a grounding of our lives.
What may surprised many, coming from a cloistered nun, is the revelation that prayer comes from a life of practical love. Sometimes we have an unrealistic vision of the cloistered life as one of ethereal and fantastical encounters with God while floating through a day of prayer. And while the life of the cloister is completely imbued with and dedicated to prayer, it has some hard realities. And in St. Teresa of Avila's time, those realities were probably a good deal harder.
What is practical love? What forms does it take? What do our lives look like grounded in practical love? It would depend upon one's state in life, one's means, one's personality and inclination. But regardless of these three it will always show in a willingness to share what God has given us with those less fortunate, less knowledgeable, or less aware of God and His Mercies. A life of practical love will always be a life of sacrifice. We will give ourselves up and surrender to the ones we love much of our energy, time, talent, and the goods of the world that have been bestowed upon us. As parents in means serving our children and bringing them up in a way that will foster their service to God, neighbor, and country. It often means long hours of what seems thankless work and doing things we don't particularly care for in correcting and instilling discipline in our children. Yes, there are great rewards and joys in this service, and that is the consolation of many acts of practical love. But practical love is based on these consolations, but on the purest love of God that makes a person constantly hunger and thirst for ways to show that he or she loves God. Practical love stems from the desire to make manifest to God, to ourselves, and to the world the overflowing love with which God fills us as His own unmerited gift of grace.
Practical love is substantially grounded and completely devoted to "other." And practical love is, well, practical and commonsense. You don't hand a starving many a worn coat. You don't give to the naked a can of baked beans. This should go without saying, but often, we are trapped in our own sense of what needs might be and we don't see far beyond our own borders.
Practical love is simply the natural outpouring of the love God pours into us as we come to know Him better. It overflows, it cannot be contained, and so it spills out in the light of the world in small acts and in large, but all of them flow from a deep and abiding love God has for us. We become Him as we pour out His love on all the Earth, seeking to return some little for the vast fortune He has bestowed upon us.
