Psalm 32: Forgiven and without iniquity imputed.

David was not so different from lowly kids, in his younger years.  In fact, he was the lowly shepherd, probably youngest of his lot, chosen for that somewhat thankless menial task, while his elders went into battle against the Philistines.

I tend to think a David of today would be a fast food worker or something, not a shepherd, but something more common.  Not a farmer kid driving a brand new truck at all, but something, again, more common, perhaps even not having a car, like walking to and fro.

When the giant was taunting the mighty army of the Hebrews, David was appalled that his forbears were unwilling to meet the challenge, and indeed, it seemed obvious to David that the Hebrews were mightier than that one.

Nationalism knee-jerk reaction.  Pride in one's own group.  And yet, David knew, not only the track record of Israeli conquest, but that God had chosen them all as his own people, bestowing what churches today call in the tax records, "intangible spiritual benefits", and yet there was more.  We guess.  They were blessed is the point, and David knew it, even while his kinsmen cowered at the taunts of Goliath.

David was, like the Priest Melchisedec, a giant of the concept of faith.

He writes in Psalm 32 that the blessing of the Lord is to be forgiven of bad behavior, and furthermore, if one has a good enough spirit, then more beyond.  A two-fold part, not of works, but of God literally knowing one's thoughts, as Jesus alluded in his Sermon on the Mount, referring to fornication having a mental component, that God considered even the thought of committing a sin to be, itself, a sin.

David states further that he confessed his sin, was honest with both he and God, and being honest with God should come easy, because He knows anyway.  You can hid nothing.  Knows all.  Even, of course, the things you only thought about, but never did in reality.  This is partly while porn is considered sinful, the types of thoughts it brings, the lust.

Being honest with God should be so much easier than being honest with one's self.  We may disappoint or dismay God, but truly, we only hurt ourselves in being dishonest with ourselves.  And maybe we pretend the best of motives, but there is always a porkchop dangling from a stick somewhere ahead of us, whether we are willing to point it out to members of the jury as evidence, or not, like maybe we even hide the prospect of reward from ourselves, in some semblance of the thoughts we harbor.  We don't even realize how selfish we can be.

But then we have Free Will, just like Adam and Eve.  Just as much as we can choose to eat the forbidden fruit, we can turn away, and maybe, if we hope, if we think on this, we can turn our selfish motivations towards the good of others and the glorification of God.
