A Purified Heart for the Lord Alone

The Lord says, 
What is making the people sick? What is causing their stomachs to turn? It is the mixture of their spiritual food. They declare My Name but add to it. They worship Me while saying their chants and emptying their minds and bowing to other gods and to people. I Am not a God to tolerate Mixture. I Am not One who has an equal or peers. I AM THE LORD GOD MOST HIGH. THE GOD OF ABRAHAM, ISAAC & JACOB. I WILL NOT SHARE MY GLORY WITH ANOTHER.
