“With a weak faith and a fearful heart many a sinner stands before the altar. But it is not the strength of his faith, but the perfection of the sacrifice, that saves; and no feebleness of faith, no dimness of eye, no trembling of hand, can change the efficacy of our burnt-offering. The vigour of our faith can add nothing to it, nor can the poverty of it take anything from it.
Faith, in all its degrees, still reads the inscription, ‘The blood of Jesus Christ His Son cleanseth us from all sin;’ and if at times the eye is so dim that it cannot read these words, through blinding tears or bewildering mist, faith rests itself on the certain knowledge of the fact that the inscription is still there, or at least that the blood itself (of which these words remind us) remains, in all its power and suitableness, upon the altar unchanged and uneffaced.
God says that the believing man is justified: who are we, then, that we should say, ‘We believe, but we do not know whether we are justified?’ What God has joined together, let not man put asunder.”
–Horatius Bonar, The Everlasting Righteousness; or, How Shall a Man be Just with God? (Carlisle, Pa.: Banner of Truth, 1874/1993), 23-4.
