Unlike you, I will not claim you have not read the scriptures. Let me quote it to you 2 Sam 12 and you tell me how you interpret the words in bold, I will be most interested if there is one that will interpret the words differently. KJV.
13 And David said unto Nathan, I have sinned against the Lord. And Nathan said unto David, The Lord also hath put away thy sin; thou shalt not die.
14 Howbeit, because by this deed thou hast given great occasion to the enemies of the Lord to blaspheme, the child also that is born unto thee shall surely die.
15 And Nathan departed unto his house. And the Lord struck the child that Uriah's wife bare unto David, and it was very sick.
16 David therefore besought God for the child; and David fasted, and went in, and lay all night upon the earth.
17 And the elders of his house arose, and went to him, to raise him up from the earth: but he would not, neither did he eat bread with them.
18 And it came to pass on the seventh day, that the child died. And the servants of David feared to tell him that the child was dead: for they said, Behold, while the child was yet alive, we spake unto him, and he would not hearken unto our voice: how will he then vex himself, if we tell him that the child is dead?
19 But when David saw that his servants whispered, David perceived that the child was dead: therefore David said unto his servants, Is the child dead? And they said, He is dead.
20 Then David arose from the earth, and washed, and anointed himself, and changed his apparel, and came into the house of the Lord, and worshipped: then he came to his own house; and when he required, they set bread before him, and he did eat.
21 Then said his servants unto him, What thing is this that thou hast done? thou didst fast and weep for the child, while it was alive; but when the child was dead, thou didst rise and eat bread.
22 And he said, While the child was yet alive, I fasted and wept: for I said, Who can tell whether God will be gracious to me, that the child may live?
23 But now he is dead, wherefore should I fast? can I bring him back again? I shall go to him, but he shall not return to me.
And in Romans 4, Paul stated
6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered.
8 Blessed is the man to whom the Lord will not impute sin.
To me, David could not be talking about himself in this passage, because his adultery sin was imputed to him, leading to the death of his son. But he saw us being so blessed under the new covenant, that the Lord will never ever impute our sin to us.
