"But GOD says this to the wicked:
'What right have you to mouth MY laws,
or to talk about MY Covenant?
You hate MY commands
and cast MY words behind you.
You join a thief when you meet one;
you keep company with adulterers.
You have a mouth of evil
and a deceitful tongue.
You speak ill of your brother,
and slander your own mother's son.
Because I was silent while you did these things,
you thought I was like you.
But now I rebuke you
and make this charge against you.
Give this a thought, you, who forget GOD;
lest I tear you to pieces with no one to help you.
Those who give with thanks, offerings, honor ME;
but the one who walks blamelessly,
I will show him the salvation of GOD.'"
- Psalm 50:16-23
(Lip service is not enough, nor is outward ritual observance. The announcement is introduced with solemnity. It uses a poetic devise called 'theophany,' in which, GOD appears as the LORD of nature. HIS people offer sacrifices which GOD does not need. With great candor, the psalmist presents GOD as condemning HIS own people for mistaking the outward ritual for the religion of the heart: honesty, purity, kindliness. These are the true sacrifices of thanksgiving. The lesson is applicable to us all. The liturgy must have self-involvement as its purpose. The offering we make is the offering of ourselves in union with the sacrifice of CHRIST.
GOD is coming to judge HIS people. HE condemns those who replace the obedience of the heart, with offerings and material sacrifices, and those who recite the commandments, instead of practicing them.)
