It means we did not put our souls into His hands.

If during the Divine Liturgy we indulge in everyday concerns and our attention at this hour is entertained by them, leaving the praise of God, then it means that we did not put our souls into His hands.
If we leave the morning prayers, instead indulging in sleep and resting on couches, and spend the time of evening praise in drunkenness and drinking, as if nailed to their place, then again, it means that our souls are not in the hands of God.
If during the Divine service, and especially on the holy days of the Lord, we leave the church and prowl around the city, arranging our affairs and meetings and walking around the squares and streets, then our souls are not in the hands of God.
If, being present at the Divine Liturgy, we abandon prayer and praise and talk with each other about worldly affairs and concerns, it means that we have not delivered our souls into the hands of God.
Saint John Chrysostom
