Indeed it is (King David did it so). In fact I think this is the
basis of how to get right with God in any case, even in
Christianity.
Of course the Christians have this curious idea that indeed this
forgiveness has bodily come through a period known as the
incarnation. And what's more it in the direction of the
incarnation's sacrifice that the contrite heart and seeking of
forgiveness must be directed.
Why it is so I have yet to comprehend, and perhaps even ask this
question 'Did you really have to die for me?'. It's a strange
question for a man drowining in sin such as myself to ask, when the
safety bouy and rope is finally thrown to me that I start to ponder
the rationale of method of my rescue.
If you ask me if why can't God just simply forgive any offense,
without having to make any of that complicated thing as the
incarnation. I shall say I don't have any idea beyond the fact that
he seemed not only concerned with simply pardoning us, but also in
showing that pardon in such a concrete way as to become incarnate,
be torn apart by His very own creation, stripped naked and hung up
to die.
It's just my guess but maybe He wasn't just interested in showing
us His forgiveness, but also to show and help us understand a small
bit of His measure of Love. And perhaps also to provide a specified
direction to which all of humanity can now move, a living, breating
example for the renewed state of man to which we will all one day
become.
The humble and contrite heart is made perhaps even more humble and
contrite when it realizes that God crazily (in human terms) decided
to do something seemingly quite unnecessary for it. And perhaps
it's just the start of something new.
