Theophan

Everywhere and always God is with us, near to us and in us. But we are not always with Him, since we do not remember Him; and because we do not remember Him we allow ourselves many things which we would not permit if we did remember. Take upon yourself this task – to make a habit of such recollection. Make yourself a rule always to be with the Lord, keeping your mind in your heart, and do not let your thoughts wander; as often as they stray, turn them back again and keep them at home in the closet of your heart, and delight in converse with the Lord.
