We live in a fallen and sinful world. What Adam and Eve set into motion at the beginning of the world, reaps heartache for us in this world. We all die, sooner or later. That is the theology.
The response of love, is that I am deeply sorry for your loss. You will never be the same, but you can eventually grieve and find a new person inside. You will never forget your son, and the hurt and sting is bitter right now. I pray that God will touch you and show you that he loves you, and he cares for you, even though your son passed away.
"Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, [SUP]4 [/SUP]who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God. [SUP]5 [/SUP]For as we share abundantly in Christ's sufferings, so through Christ we share abundantly in comfort too" 2 Cor. 1:3-5
