3 For I acknowledge my transgressions: and my sin is ever before me.

He to whom much is forgiven, the same loveth much - Lk 7: 47

A balance was needed. A thorn in the flesh. Something to ever remind him of the pitiful weakness and insecurity of the best and strongest of human nature.

The sin changed the whole course and pattern of David's subsequent life, both internally within himself and externally in his experiences and circumstances-

"The sword shall never depart from thine house" (2 Samuel 12:10).

The point is not, how could such a man do such a thing? The point is: If such a man could do such a thing, how vigilant must we be to constantly strengthen our defences against the deceptiveness of sin. Jesus said to Peter-

"Watch and pray lest ye enter into temptation" (Matthew 26:40)-

Bro Growcott - BYT 4.7.

5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.

The Christ-Deity veiled himself in the Adamic nature defiled by sin,‭ ‬in order that he might condemn sin to death in the nature which, though created "very good," had legally defiled itself by transgression of the Eden law. This purpose would have been defeated if he had veiled himself in a clean nature.

To say that the Man,‭ ‬Jesus, was corporeally clean, or pure, holy, spotless, and undefiled, is in effect to say that he was not "made of a woman;" for Scripture teaches, that nothing born of woman can possibly be clean: but it is credibly testified that he was "born of a woman;" he must therefore necessarily have been born corporeally unclean. Hence, it is written of him in Psa 51:5

‭"‬I was shapen in iniquity; and in sin did my mother conceive me."

He therefore prays,He therefore prays,

"‬Purge me with hyssop and I shall be clean; wash me, and I shall be whiter than snow."

This prayer has been answered,‭ ‬and he has been "Washed thoroughly from his (corporeal) iniquity, and cleansed from his sin;" so that now he has a clean nature, which is spirit and divine-"the Lord the Spirit"- once dead as to flesh, but now alive as Spirit for evermore Rev 1:18.

9 Hide thy face from my sins, and blot out all mine iniquities.

Now, what does this state of mind arise from? Its very kernel, without which it could have no existence is this: the belief in God, the recognition of His loving power and presence, the sense of His personal acquaintance with all our ways, and of His supreme and sovereign proprietorship and authority over us as His creatures.

How could a man have any distress towards God because of sin who had any doubt as to the existence of God? Still less, how could such a man be animated by the love that David expresses towards God in all the Psalms? It is manifest that the first condition of this state of mind is knowledge.

Bro Roberts - The inside of the Truth

10 Create in me a clean heart, O Elohim; and renew a right spirit within me.

Assimilating the spirit word into the heart (not just the intellect) continually, is the process of washing the heart clean Eph 5:26.

Enlighten the intellect, purify the heart and pray (Rom 8:14).

17 The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.

Every natural disappointment can and should be a thankful stepping-stone to greater peace with God, for by contrast to all things and persons human it emphasizes the unassailable dependability of that peace.

What we grieve over as a loss, or disappointment, or deprivation, may be a great emancipation and deliverance and opportunity, a fresh turn of our lives in a higher and more satisfying direction.

God's ways of teaching and correcting us are strange and wise and beautiful. The sweetest, deepest scent is from the crushed flower. Natural disappointment and sorrow can be the golden portal to spiritual joy.

Joy that is born of sorrow is a far fuller and stronger-rooted joy. Above all things, never let yourself be sorry for yourself. This is sick, fatal, dead-end folly. That is a reproach on God's love.
