Book of Acts - Chapter 1 - Verse 26

After the betrayal and subsequent death of Judas Iscariot, the remaining eleven apostles gathered to select a replacement to bring the number back to twelve. They did so by casting lots, a common practice in biblical times used to make important decisions. The process involved each apostle writing the name of a suitable candidate on a stone or piece of wood, placing them into a container, and then drawing one out at random. In this instance, the lot fell to Matthias, who was then officially recognized as one of the twelve apostles. This event highlights the apostles' commitment to ensuring the continued integrity and completeness of their group by following the guidance of the Holy Spirit in their decision-making process. Matthias's selection serves as a demonstration of God's sovereignty and his hand in orchestrating the affairs of his people, even down to the smallest details.
