Christ's Sacrifice And Man's Appropriation

One thing in this passage remains to be noted, and it is of the first importance. It is said of the blessed ones that "they washed their robes and made them white in the blood of the Lamb."

Here is symbolically laid down man's part in his own salvation; the blessed ones washed their own robes. That is to say, the act of man's redemption is Christ's, but the effect is not passive and man has to appropriate it. There might be available to a man all the apparatus to cleanse his garments, but it remains ineffective until he uses it for himself.

How does a man avail himself of the sacrifice of Christ?

He does so through penitence. He must begin with sorrow for his sin and the desire for amendment. He does so through faith. He must believe with all his heart that Christ lived and died for us men and for our salvation, and that his sacrifice is mighty to save. He does so through using the means of grace. The Scriptures will awaken his penitence and his faith and kindle his heart; prayer will keep him ever close to Christ and daily increase his intimacy with him; the Sacraments will be channels through which by faith renewing grace will flow to him. He does so through daily loyalty and vigilance and living with Christ.
