Free will is what has made evil possible. Why, then, did God give [creatures] free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having.
Jesus wants to pray with us and to have us pray with Him, so that we may be confident and glad that God hears us. When our will wholeheartedly enters into the prayer of Christ, then we pray correctly…and with Him we also know that we shall be heard.
He [Christ] tells us plainly, and without any qualifications, that we are involved in a war in which there is no room for neutrals. Yet people attempt to evade His statement. Generally speaking, these are the very people who are the quickest in laying the blame upon God for all the sorrow and sin in the world. They argue that He could prevent it. They excuse their own do nothing attitude by making of evil’s apparent predominance a ground for doubt of His loving kindness. It never seems to occur to them to look for the cause in mankind.
Nothing harms or destroys us but the wrong use of that liberty of choice which God has entrusted to us.
