Vigilance is necessary for holiness. Christians are called to be prophetic by keeping watch for the Lord. St. Monica was a vigilant woman, and her holiness inspired and saved St. Augustine and many others.
Jesus comes into our consciousness unexpectedly. He is always present and our awakening to His being near is a reminder that every disciple must be vigilant.
O gracious God, may I keep an eye out for you today. I know that you are always present. It is I who wanders and loses focus. Help me to be watchful today.
