“Furthermore, they have defiled my Temple and violated my Sabbath day! On the very day that they sacrificed their children to their idols, they boldly came into my Temple to worship! They came in and defiled my house.”

~ Ezekiel 23.38-39 NLT

God expects full-on devotion to him and him only. Whatever competes with God in my heart and mind, I need to remove it.

"No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and mammon [money, possessions, fame, status, or whatever is valued more than the Lord]."

~ Matthew 6.24 AMP

Dear God
help me be focused on you
and you alone

See: Jealous for me
