50:8-9, 16bc-17, 21 and 23
R. (23b) To the upright I will show the saving power of God.
"Not for your sacrifices do I rebuke you,
for your burnt offerings are before me always.
I take from your house no bullock,
no goats out of your fold."
R. To the upright I will show the saving power of God.
"Why do you recite my statutes,
and profess my covenant with your mouth,
Though you hate discipline
and cast my words behind you?"
R. To the upright I will show the saving power of God.
"When you do these things, shall I be deaf to it?
Or do you think that I am like yourself?
I will correct you by drawing them up before your eyes.
He that offers praise as a sacrifice glorifies me;
and to him that goes the right way I will show the salvation of God."
R. To the upright I will show the saving power of God.
God does not want our sacrifices if we insist on living in sin. He will show us our sins, make them apparent to us. Until we correct those, and live according to the right way, our sacrifices will be rejected.
So many of us think that if we say our prayers, make our charitable donations, do our good works, that God will look the other way if we lead a second, sinful life. He is always ready to forgive, but to receive forgiveness, we have to repent. And repentance is false - a bald-faced lie to God, if we know that we will turn back to that sin tomorrow.
We have to live His precepts first. That is the only sacrifice that He truly wants. Once we do that, we can offer true sacrifices - fasting, alms-giving, charitable works, mortifications, prayers - not as a quid pro quo for behavior we know to be wrong but indulge in anyway, but as simple, unselfish demonstrations of our love.
What means more to a woman: flowers given spontaneously out of love, with no ulterior motive? Or flowers given as an apology for a wrong that both she and her husband know he will commit again? If I say to her, "Sorry about lying to you, here are some flowers. I love you. But I will probably lie to you again tonight," she will probably throw those flowers in the trash. We should not treat our spouses that way, and we should not treat God that way.
We should first stop sinning and amend our lives, and stop focusing on ways to try to make up for our regular and habitual sin.
