The Bible says so. God’s judgment to David was,
“Thou hast killed Uriah the Hittite with the sword”(2 Sam. xii. 9).
But that didn’t make David a hopeless murderer (1 John iii. 15), any more than being guilty of telling a lie makes a man a hopeless liar (Rev.xxi. 8). David’s repentance was genuine in the extreme, and accepted by God, who said:
“The Lord hath put away thy sin” (2 Sam. xii. 13);
and, therefore, not a cursed man, but a blessed one (Psalm xxxii. 2). A lover of God and of good men will have no parley with the Pharisaical infidels who dare to refer to David as a wicked king. In spite of his sin he was a man after God’s own heart (1 Sam. xiii. 14; Acts xiii. 22).
