Hebrews 4:7 He again fixes a certain day, “Today,” saying through David after so long a time just as has been said before, “TODAY IF YOU HEAR HIS VOICE, DO NOT HARDEN YOUR HEARTS.”
To recognize God's presence, you must be conscious of the here and now. It means more than just occupying space in a given situation but actually paying attention. It means being fully engaged in the now. Not distracted by memories of the past or worries of the future.
