Zeal is a fervent passion or enthusiasm, especially in matters of faith. While having zeal for God is commendable, it must be accompanied by a correct understanding of His will and teachings. Enthusiasm without knowledge can lead to misguided actions, as it may not align with the truth of God's word. This passage encourages believers to pursue a balanced faith, where passion is informed by a deep understanding of scripture and God's character.
In the context of the early Christians, many were zealous for God but lacked the full understanding of the righteousness that comes through faith in Christ. This serves as a reminder that our spiritual journey should be marked by a continuous pursuit of knowledge and wisdom, ensuring that our actions and beliefs are rooted in the truth. By seeking both zeal and knowledge, we can live out our faith in a way that truly honors God and reflects His love and truth to the world.
