The answer
King David is indeed a great hero of faith. No human being is perfect. That is why Biblical writers did not write only of King David's greatness; but also of his weakness. They showed David as someone who loved God; but at the same time was tempted by thirst for power and his own sensual desires.King David had paid dearly for all his shortcomings. Family strife followed him later in life until his death. He dealt with his wives' jealousy and strife, his son’s rebellion, and his disputed succession.
In spite of all these tribulations, King David's virtues of devotion to God, valor in war, loyalty, and faithfulness in friendship was so inspiring; that despite his many faults, he was seen as a great king and prophet, described by God as “a man after My own heart”.
