…and set a watch… – Nehemiah 4:9

You and I, dear friends, have need to set a watch against the enemies of our holy faith… A night-watchman’s place is not an easy berth; but I am willing to take that post for my blessed Master’s sake. Those professed servants of Christ who enter into an unholy alliance with men who deny the faith will have to answer for it at the last great day. As for us, brethren, when our Lord comes, let Him find us watching as well as praying.

But, dear friends, to come home to ourselves, we must set a watch against our own personal adversaries. I hope that, in one sense, you have no personal enemies; that you own nobody a grudge; but that you live in peace and love towards all mankind. But there are Christian people here, who will go to homes where everybody in the house is against them. Many a godly woman goes from the sanctuary to a drunken husband; many children, converted to God, see anything but what they like to see in their homes. What are they to do in such circumstances? Set a watch. Dear woman, how do you know but that you shall be the means of saving your unconverted husband? If so, you must set a watch; do not give him a bit of your mind; you will not convert him that way. And you, dear children, who have come to Christ, and joined the church, mind that you are dutiful and obedient, for otherwise you will destroy all hope of bringing your parents to the Saviour. Set a watch. “Oh!” say you, “if I do a little wrong, they magnify it.” I know they do; therefore, set a watch; be more careful. Set a watch over your temper, set a watch over your tongue, set a watch over your actions. Be patient, be gentle, be loving. May the Spirit of God work all this in you! ~ C.H. Spurgeon
