Look steadily at Jesus on the cross, if you want to feel inward peace. Look to anything of your own, and you will never feel comfortable. Your own life and doings, your own repentance, your own morality and regularity, your own church-going, your own Bible-reading and your prayers, what are they all but a huge mass of imperfection? Rest not upon them for a moment, in the matter of your justification. As evidences of your wishes, feelings, bias, tastes, habits, inclinations, they may be useful helps occasionally. As grounds of acceptance with God they are worthless rubbish. They cannot give you comfort; they cannot bear the weight of your sins; they cannot stand the searching eye of God. Rest on nothing but Christ crucified, and the atonement He made for you on Calvary. This, this alone is the way of peace.
