The truth is, that many believers today are afraid of being criticized and have lost boldness in their faith. They have become victims of secular and religious wet blankets who object to anything that might be considered as Christian fire. According to J. C. Ryle:
“It is always good to be zealous in a good cause.” (Galatians 4:18)
Where is your zeal for the glory of God? Where is your zeal for extending Christ’s Gospel through an evil world? Zeal, which was the characteristic of the Lord Jesus—zeal, which is the characteristic of the angels—zeal, which shines forth in all the brightest Christians; where is your zeal, unconverted reader—where is your zeal indeed? You know well it is nowhere at all. You know well you see no beauty in it. You know well it is scorned and cast out as evil by you and your companions. You know well it has no place, no portion, and no standing ground, in the religion of your soul. It is not that you know not what it is to be zealous. You have zeal—but it is all misapplied. It is all earthly. It is all about the things of time. It is not zeal for the glory of God. It is not zeal for the salvation of souls. Yes! many a man has zeal for the newspaper—but not for the Bible—zeal for the daily reading of the “Times,” but no zeal for the daily reading of God’s blessed Word. . . .
Reader, if this is your case, awake; I do beseech you, to see your gross folly. You cannot live forever. You are not ready to die. You are utterly unfit for the company of saints and angels. Awake! Be zealous and repent. Awake to see the harm you are doing. You are putting arguments in the hands of infidels by your shameful coldness. You are pulling down as fast as ministers build. You are helping the devil. Awake! Be zealous, and repent. Awake to see your childish inconsistency. What can be more worthy of zeal than eternal things—than the glory of God—than the salvation of souls? Surely if it is good to labor for rewards that are temporal, it is a thousand times better to labor for those that are eternal. Awake! Be zealous, and repent. Go and read that long-neglected Bible. Take up that blessed Book, which you have, and perhaps never use. Read that New Testament through. Do you find nothing there to make you zealous, to make you earnest about your soul? Go and look at the cross of Christ. Go and see how the Son of God there shed His precious blood for you—how He suffered and groaned, and died for you. How He poured out His soul as an offering for sin, in order that you, sinful brother or sister, might not perish—but have eternal life. Go and look at the cross of Christ, and never rest until you feel some zeal for your own soul—some zeal for the glory of God—some zeal for extension of the Gospel throughout the world. (Be Zealous)
