Faith is comforted twice over in relation to God’s power. First, because it knows that he has ample ability to do good. Thus, in order to further the salvation of believers he puts forth his hand to rule and govern all things; heaven and earth are his possession and domain, and every creature depends on his goodwill. Faith is comforted in the second place because it finds ample assurance in his protection, since whatever might do harm is subject to his will, and the devil and his devices are restrained as by a curb. Everything, in short, which might impede our salvation is subject to his control.
– John Calvin
