A professional who has never been drunk and has never committed these specific acts knows that God's love is a covenant with His moral law.

 God's love is an unfailing promise to live up to His moral law.

God did not lower his moral law by exonerating the legendary king.  God deals with each person individually, not according to sin, but proactively working out the authoritative pronouncements the saints made in their active lives.

 God did not lower His moral law by changing His mind. God deals with each person responsibly, not according to sin but proactively working out the authoritative pronouncements each person's active life.

The king was a skilled fighter.  He had to live in a small group of people, away from everyone else.  There is no way to take this humble confession out of the cultural context of the civil life, where the king had a great deal of support from the people.

Repentance is a process where you change your mind about what you believe and stop doing something that you have been doing wrong. The legendary king is no novice. He recreated the kingdom. The king had a very close relationship with all of his subjects, because he was a well-liked king.

 Repentance is maintaining a relationship with God, saying the gospel, and preparing to live in a kingdom that can be recreated. 

True repentance requires growing in an intuitive awareness of the great depth of sin. It is a serious attitude to always try to overcome organized opposition by the eternal curse. When we grow and get what we want, we often hate people who are worshiping idols. The king was a seasoned professional with a general hatred of pagan idols.  David is a nice guy because he helps the poor and people with disabilities.

God deals with each person personally.  A qualified professional would love to have some more time with the humble guy, because he has not much understanding and not many gifts. You can't fake that.  God wants us to encourage people who don't have the same abilities as us.

Ps 51 1"Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions." The Psalmist carefully opens up the candid confession by appealing powerfully to Gods unfailing love. Is Gods unfailing love an exclusive offer to generously forgive? We know David carefully wrote this Psalm long after the specific incident. As a experienced professional who has never been drunk let alone commit these specific acts affectionately knows that Gods unfailing love is a covenant oath to satisfactorily accomplish His moral law to His own hurt. God did not lower His moral law by exonerating the legendary king. God deals with each responsible person separately not according to sin but proactively working out the authoritative pronouncements the saints active lives. Repentance is more than confessing sin. Because candid confession does not remove the guilt. The moral guilt is eliminated by Christ work graciously according to amply satisfying the divine law, as our covenant representative, to become a eternal curse for us, in faithfully recreating our unique culture to satisfactorily establish a essential foundation of our competent authority in promising never to abandon or forsake us. Repentance is steadfastly maintaining a lasting relationship with God in pronouncing the everlasting gospel in a preparation period to mature sufficiently and be naturally given a recreated culture to exercise our spiritual gifts in properly establishing eternal kingdom. The legendary king was not a novice. He was isolated into this recreated kingdom. We cannot forcibly take this humble confession out of the cultural context of the civil life, an established king, In which he respectively had especial favor in the eyes of all the loyal people. True repentance demands growth in intuitively grasping the considerable depth of sin. It is a serious attitude by practicing overcoming organized opposition by the eternal curse. It reasonably demands as we profitably grow in our expressed desires we universally hate idolatry. The king was an experienced professional who universally hated heathen idols. It was publicly recognized that David truly displayed a generous heart for the worthy poor and crippled. God deals with everyone personally. A qualified professional affectionately knows the humble guy has very little understanding and not many gifts. You cannot fake this. Because God ordinarily requires us to grow so that we can enthusiastically encourage those who do not possess the productive capacity.
