2 Samuel 12:22-23 22He said, "While the child was still alive, I fasted and wept, for I said, 'Who knows whether the LORD will be gracious to me, that the child may live?' 23But now he is dead. Why should I fast? Can I bring him back again? I shall go to him, but he will not return to me." E.T, it is not easy my friend but be of good cheer and take comfort in the fact that King David says in the Scriptures that he will go someday to be with his child. So you to can also. I will pray for your family. G-d bless!
