16th Sunday in Ordinary Time

Reading 1: Genesis 18:1-10a - Abraham is revered by both Jews and Christians because he was a man of faith. He believed God's promises, even when the odds seemed to be against him. In Eucharistic Prayer I, we ask God to accept our gifts "as you accepted the gifts of Abraham, our father in faith." We are children of Abraham because we believe in God's promises to us. What promises of God do you believe in? 
We often fear the stranger at our door, and it is wise to be cautious. But that should not prevent us from "welcoming strangers" whenever we can. Have new neighbors moved in? How can I welcome them to the neighborhood? Is there someone new at school who would appreciate a friend? Do I stick with old friends at the parish coffee hour or socials, or do I "welcome strangers" as Abraham and Sarah did? Each one of us can be a messenger from God in our own way. If we neglect to welcome others, we may miss the message of God's love given to us in a new friend! In what situations could you welcome newcomers?
Reading 2: Colossians 1:24-28 - Reflect for a moment on "the mystery of Christ in you." How is Christ in you? Do you experience his presence in you? When? How does the fact that Christ is in you give you hope?
Gospel: Luke 10:38-42 - Most of our lives are a combination of Martha and Mary. (Even cloistered monks and nuns, devoted to lives of prayer, have hours of work every day.) However, if our lives are all-Martha-all-the-time, they may be out of balance. We may be missing "the better part." (There is an ironic joke that goes: "At the time of death, no one says, 'I wish I had spent more time at the office.' ") How can we put more Mary-like listening into our lives? When do we make time to listen to our families? our friends? When do we make time to listen to Jesus?
