Second in series using Psalm 111 and Daniel 9
Psalm 111:3-4
Full of splendor and majesty is his work, and his righteousness endures forever.  He has caused his wondrous works to be remembered; the LORD is gracious and merciful.

Daniel might well have had that in mind in part when he prayed:
Daniel 9:4-5
I prayed to the LORD my God and confessed and said, "Alas, O Lord, the great and awesome God, who keeps His covenant and lovingkindness for those who love Him and keep His commandments, we have sinned, committed iniquity, acted wickedly, and rebelled, even turning aside from Your commandments and ordinances."

As I noted last time, this also reminds me of Deuteronomy 7:9 where Moses stated:  "Know therefore that the LORD your God, He is God, the faithful God, who keeps His covenant and His lovingkindness to a thousandth generation with those who love Him and keep His commandments" while Deuteronomy 7:10 goes on to say, "but repays those who hate Him to their faces, to destroy them; He will not delay with him who hates Him, He will repay him to his face."

Daniel prayed accordingly, confessing both God's mercy and His judgment.  More than that, Daniel referred to the disobedient nation not as "them" but as "we," something astonishing as nowhere do we see Daniel as anything but obedient.

Two points to consider:
1. Daniel included himself in the "we" in beginning his confession; why? 
2. Think of the many ways Daniel described sinning:  sinned, committed iniquity, acted wickedly, turned aside from God's commands and ordinances; how many ways do we describe sin?  Are we easy on ourselves, as if to say, if my sins are not acted out, they aren't as significant as those which are?  See Matthew 5-7 for further consideration.
