One needs to start at the beginning and work their way to the end. And like the monks and the Hebrews of old, we need to mouth these words to ourselves and God (even if in our minds), pondering their meaning as well as lifting them as prayer to God.
If we don't learn to be sensitive to our sin both in recognizing it, as well as in agreeing with God about it, then we need to ask God to give us that sensitivity. To be aware of our sins will help us to become aware of our salvation and of our Savior and Lord God, as we learn more and more to respond to this awareness in the ways David writes for us in this psalm.
To pick out one line as a favorite is like picking out one photo among the photos of wonderful scenes of creation. But one part I especially find compelling within the whole are these lines:
My sacrifice, O God, is a broken spirit;This is part of the heart that God wants from us his people. One that is not beating one's breast or back over and over, but one that is rightfully broken before God because of sin in one's life, be they "big" or "little" sins, accompanied by deep sorrow and repentance. This is the sacrifice that will make all other sacrifices acceptable and even delightful to God.
a broken and contrite heart you, God, will not despise.
I find this more important for me as I go on through the years of seeking to follow Christ. What about you? What thoughts do you draw from this? Or thoughts you would share with us?
