From the Book of Jeremiah the Prophet (7:22-24) we read:
In speaking to your ancestors on the day I brought them out of the land of Egypt, I gave them no command concerning burnt offering or sacrifice. This rather is what I commanded them: Listen to my voice; then I will be your God and you shall be my people. Walk exactly in the way I command you, so that you may prosper. But they did not listen to me, nor did they pay attention. They walked in the stubbornness of their evil hearts and turned their backs, not their faces, to me.
Once again the Lord tells us that the worship he is really seeking from his people together and from each of us individually within his people (the Church) is righteous living, i.e. day by day putting his commandments into practice. In this passage there is an added note about turning their faces to God, i.e. looking at the Lord eye to eye, total honesty from the heart that loves him. Our Lenten goal has been to contemplate the face of Christ.
