Whenever any distrust arises, and all means of escape are taken away from us, whenever, in short, it appears to us that everything is in a ruinous condition, let us recall to our remembrance that Christ is called Wonderful, because he has inconceivable methods of assisting us, and because his power is far beyond what we are able to conceive. When we need counsel, let us remember that he is the Counsellor. When we need strength, let us remember that he is Mighty and Strong. When new terrors spring up suddenly every instant, and when many deaths threaten us from various quarters, let us rely on that eternity of which he is with good reason called the Father, and by the same comfort let us learn to soothe all temporal distresses. When we are inwardly tossed by various tempests, and when Satan attempts to disturb our consciences, let us remember that Christ is The Prince of Peace, and that it is easy for him quickly to allay all our uneasy feelings. Thus will these titles confirm us more and more in the faith of Christ, and fortify us against Satan and against hell itself.
