Study universal holiness of life. Your whole usefulness depends on this, for your sermons last but an hour or two; your life preaches all the week. If Satan can only make a covetous minister a lover of praise, of pleasure, of good eating, he has ruined your ministry. Give yourself to prayer, and get your texts, your thoughts, your words from God. Luther spent his best three hours in prayer.—Robert Murray McCheyne
Indeed, McCheyne's words still speak to all of us today, not just ministers of the Word. Sunday is our day of rest, rejuvenation, learning and fellowship with the saints. On Monday we return to the hard work of living in this sinful world. Learn holiness on the Lord's Day, apply it on Monday and through the week. Let's live radical lives and show the world that we are different, not just an Americanized version of Christianity.
