With reference to Prophet Isaiah's vision, which of the following attributes must a minister of God possess?

According to Prophet Isaiah's vision, a minister of God must possess holiness, which is the state of being pure, blameless, and set apart for God's use. In Isaiah's vision, he saw God sitting on a throne, and the seraphim around Him were declaring His holiness. This emphasizes the importance of holiness in the ministry. Dedication and knowledge are essential attributes that a minister should possess, but they are not explicitly mentioned in Isaiah's vision. Anointing is also crucial, but it flows from holiness. In other words, a minister who is holy is more likely to be anointed by God for His service. Therefore, holiness is the primary attribute that a minister must possess according to Isaiah's vision.
