A starling never reveals the richness of its hues until we see it in the sunlight. A duty never discloses its beauties until we set it in the light of the Lord. It is amazing how a dull road is transfigured when the sunshine falls upon it! God's grace reveals the graces in all healthy things. Hidden lovelinesses troop out when we set them in the presence of the Lord.

And so the Apostle counsels an obedience which is "in the Lord." He wants us to know how beautiful common things can be when they are linked to Christ. And what he says about obedience he says about everything. One of the great secrets in the teaching of Paul is expressed in just this phrase, "in the Lord," "in Christ." It meant connection with a power-house whose energy would light up all the common lamps of life -- the lamps of hope, of faith, of love, of daily labour, and of human service.

And this is the secret of the Christian life. We need no other; at least, all other secrets are involved in this. If we attend to this little preposition "in," we have entry into the infinite. If we are "in Christ," we are in the kingdom of everything that endures, and we are outside nothing but sin.
