How do we know God chooses His leaders?

The selection of leaders in the Church, such as Matthias to replace Judas Iscariot, illustrates God's sovereign choice in appointing those who will fulfill His divine purposes. In Acts 1:24-26, the apostles prayed for guidance from the Lord, acknowledging that He alone knows the hearts of men, thus seeking His will in choosing Matthias. This prayerful reliance on divine sovereignty reflects the Reformed understanding of God's active governance in all aspects of life, including leadership within the Church. The anecdote of God's choice of David (1 Samuel 16:7) reinforces this idea, highlighting that God looks at the heart rather than outward appearances. Through these examples, we see that leadership in the Church is not based on human assessment but is implemented through God's providential will.
