Romans 5:10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. 11 And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement. 12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.
Let me ask you a question. Do you have joy in your life? The joy of knowing your sins are forgiven? That you were once condemned to an eternal hell but were miraculously saved from it? That it didn't cost anything other than a little faith? Depressed? Far from it. It is the folks that don't have this promise firmly in their grasp that have reason to be depressed.
My guy's father gave him one of the best explanations I've heard concerning why he would never commit adultery. Aside from loving his wife - he said that "it's just incredibly rude."
Putting your own needs above those of your spouse and family - is the ultimate inconsiderate act.
