Four things are here taught, as a Christian's directory for his day's work. When to awake; Now; and to awake out of the sleep of carnal security, sloth, and negligence; out of the sleep of spiritual death, and out of the sleep of spiritual deadness. Considering the time; a busy time; a perilous time. Also the salvation nigh at hand. Let us mind our way, and mend our pace, we are nearer our journey's end. Also to make ourselves ready. The night is far spent, the day is at hand; therefore it is time to dress ourselves. Observe what we must put off; clothes worn in the night. Cast off the sinful works of darkness. Observe what we must put on; how we should dress our souls. Put on the armour of light. A Christian must reckon himself undressed, if unarmed. The graces of the Spirit are this armour, to secure the soul from Satan's temptations, and the assaults of this present evil world. Put on Christ; that includes all. Put on righteousness of Christ, for justification. Put on the Spirit and grace of Christ, for sanctification. The Lord Jesus Christ must be put on as Lord to rule you as Jesus to save you; and in both, as Christ anointed and appointed by the Father to this ruling, saving work. And how to walk. When we are up and ready, we are not to sit still, but to appear abroad; let us walk. Christianity teaches us how to walk so as to please God, who ever sees us. Walk honestly as in the day; avoiding the works of darkness. Where there are riot and drunkenness, there usually are chambering and wantonness, and strife and envy. Solomon puts these all together, Psalm 78:18.
