Paul Tillich said in the 1960's our god is our ultimate concern. Whatever gains our ultimate attention becomes our god. We have problems with idolatry in the 21st century too.
Like Martha in the Bible, we are troubled and concerned over many things. We are concerned about work, family, marriage, health, life. Every concern is tyrannical. It wants to own our whole heart, our whole mind. It wants our infinite attention, our unconditional devotion. I saw a bumper sticker stating "Soccer Rules." In many families that is true. We develop all kinds of gods.
Maybe it's time to pledge our allegiance to the one, true, living, everlasting, God and set our feet to walking in God's ways. We believe in one God. May we see his glory in and through our lives every day.
