A person who is obsessed is characterized by committed, settled, passionate love for God, above and before every other thing and every other being.
Attention, Israel! God, our God! God the one and only! Love God, your God, with your whole heart: love him with all that's in you, love him with all you've got! Write these commandments that I've given you today on your hearts. Get them inside of you and then get them inside your children. Talk about them wherever you are, sitting at home or walking in the street; talk about them from the time you get up in the morning to when you fall into bed at night. Tie them on your hands and foreheads as a reminder; inscribe them on the doorposts of your homes and on your city gates. (Deuteronomy 6:4-9, The Message)
“And you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.” (Mark 12:30)
