Zeal in doing the will of the Lord is a truly admirable quality. In fact, the apostle Paul encouraged Christians to be “zealous for good works” (Titus 2:14, New King James Version). The apostles themselves were reminded of this quality when they witnessed Jesus cleansing the temple, recalling the words, “Zeal for Your house has eaten Me up” (John 2:13–17; cf. Psalm 69:9). Seeing the Lord’s wholehearted devotion to His Father’s will ought to inspire each of us to cultivate that same kind of zeal in our own service to God.

However, I also recognize that zeal can be misguided when it is not grounded in a proper knowledge of God’s will (Romans 10:2). Therefore, I pray not only for greater zeal but also for the wisdom to direct that zeal in the right way. In the original language of the New Testament, the word translated zeal carries the idea of earnest eagerness or fervent devotion. Such eagerness may express itself in different ways, but it must always be governed by God’s truth.

Looking at the Gospel accounts, I see that James and John were two brothers who exemplified zeal. Jesus even nicknamed them “Sons of Thunder” (Mark 3:17). On one occasion, however, their zeal was misguided. When a Samaritan village refused to receive Jesus, they asked, “Lord, do You want us to command fire to come down from heaven and consume them?” (Luke 9:51–56). Even so, they remained in fellowship with Jesus, who loved them deeply. Rather than rejecting or extinguishing their zeal, Jesus patiently corrected them, so that they would reflect God’s will instead, of mere impulse.

After the Great Commission was given and the apostles began preaching in the name of Jesus, James became the first of the apostles to be martyred (Acts 12:1–2). His zeal for the Lord remained steadfast, even in the face of persecution, exemplifying those who suffer “for righteousness’ sake” (Matthew 5:10). I pray that my own zeal will likewise be marked by such love and devotion to God, remaining faithful even if it should one day cost me my life (Revelation 2:10).

On the other hand, James’ brother John was the only apostle who was not martyred for his faith. He lived to an old age and, during the reign of Domitian, was exiled to the island of Patmos because of his unwavering testimony of Christ. Before his exile, John wrote the Gospel of John and later authored three epistles that consistently emphasized the importance of commitment to the truth and genuine love for fellow Christians (John 8:31-32; 1 John 3:18-23). While on Patmos, he received the Revelation of Jesus Christ and recorded it (Revelation 1:9). After his exile ended, early Christian tradition suggests that John returned to Ephesus, where he continued to encourage his brethren. He became especially known for his emphasis on the idea that love for one another must always accompany faithfulness to God’s truth.

Interestingly, while the apostle John was once ready to rain down fire and brimstone on the Samaritans, later in life, he stood firmly for the truth while also promoting brotherly love. There is no compromising of truth within John’s message; however, he grew to embody a great balance between his zeal for the Lord and his love for others! True love certainly entails caring enough for someone’s soul to speak whatever is necessary for their edification, but it also requires the type of tenderness that shines through in his epistles. 

For these reasons, I pray to God Almighty: help me grow in my zeal! I want to express this zeal with both the proper knowledge and wisdom, as I wish to be the person You want me to be in every one of my interactions with others. Help me to discern when to speak with firmness, and when to approach others more tenderly, O God (Ecclesiastes 3:1-8). 

Father, may I never compromise Your truth, for Your word is truth (John 17:17). May I be zealous for good works… And may I also be a good example for others, glorifying You in this way (Matthew 5:16). May Your people, everywhere, be (properly) zealous for good works (Titus 2:14; Romans 10:2). Amen.
