“Now, when a man has learned through the commandments to recognize his helplessness and is distressed about how he might satisfy the law–being truly humbled and reduced to nothing in his own eyes–he finds in himself nothing whereby he may be justified and saved.
Here the second part of Scripture comes to our aid, namely the promises of God which declare the glory of God, saying, “If you wish to fulfill the law, come believe in Christ in whom grace, righteousness, peace, liberty, and all things are promised to you. If you believe, you shall have all things; if you do not believe, you shall lack all things.” -Martin Luther, On Christian Liberty
