C.H. Spurgeon:

“God Himself, at one time, seemed to be against us: the ten great cannon of His Law were turned against our walls; all heaven and earth mustered for battle; God Himself was against us, at least, so conscience reported from her look-out. But, now, at this moment, having believed in Jesus Christ, we have entered into rest, and we have perfect peace as to our former sins. Who is he that can harm you, O ye that are reconciled to God? “If God be for us, who can be against us?” “Who shall lay anything to the charge of God’s elect?” We have by faith arrived at a state of perfect reconciliation with God. The divine Fatherhood has covered us. We inherit the spirit of children, the spirit of love and of unquestioning confidence. Everything is quiet, for we dwell in our Father’s house. Look upward, and you will perceive no seat of fiery wrath to shoot devouring flame. Look downward, and you discover no hell, for there is no condemnation to them that are in Christ Jesus. Look back, and sin is blotted out. Look around, and all things work together for good to them that love God. Look beyond, and glory shineth through the veil of the future, like the sun through a morning’s mist. Look outward, and the stones of the field, and the beasts of the field, are at peace with us. Look inward, and the peace of God, which passeth all understanding, keeps our hearts and minds by Christ Jesus. The Lord leadeth us by still waters at such happy times, along that road of which we read, “No lion shall be there.” If you who are believers in Jesus do not usually enjoy this peace, the blame must be laid to your own door: you make your own disquietude, for God saith to you, “Peace, peace,” and He will keep you there if your mind is stayed on Him. Happy is he whose conflict is ended, and whose warfare is accomplished by faith in Christ Jesus.”

Charles Spurgeon, from the sermon, The Song of A City and the Pearl of Peace
