According to the Apostles’ Creed, the almightiness of God is an essential part of the Christian faith. In the late Middle Ages a distinction was made between the absolute power of God and God’s ordained power. On the one hand, God can do everything, on the other hand He can only do what he has stipulated (ordained). However, Luther used this distinction very little in his theology.
The almightiness of God meant for Luther ‘all-working’. All excitements and thoughts are utilized by God. God works mightily everything in everyone. For Luther almightiness is a descriptive category used to understand God as the Creator and Sustainer of this world. God’s almightiness is a reason for Christians to thank Him before that. On the other hand, God works also through the devil and He utilizes even the wrong.
