Today's first reading at Mass came from Philippians 2. The verse that stood out for me is 3a: "Do nothing out of selfishness or out of vainglory." In other words, we must be selfless. Jesus is totally selfless and he is free. Hence the secret of becoming free is to abandon ourselves in God. We cannot fly in space like the birds, but we can soar in Christ with total freedom. What a contrast to living selfishly with all our heavy burdens!
