There are such great consolations and promises in these Psalms of Ascent. One that popped out today is from Psalm 130. How good is this?
If the Lord were to count iniquities against us, we'd all be hosed. But with Him instead we find forgiveness.
And then this: we find forgiveness that He should be feared.
Now just how good is that? We have forgiveness so that God can get the appropriate and well-deserved praise from hearts that are rightly oriented before Him. Rightly understood, forgiveness produces worship and the kind of reverence that makes us not want to sin and thus need more forgiveness.
