How do we know that prayer is vital for church leaders?

In choosing His apostles, Jesus set a precedent for the importance of prayer in the selection and ordination of church leaders. His example of praying all night before making this significant decision teaches that those involved in ministry need to seek God's guidance to ensure that those being ordained are truly called and equipped by the Holy Spirit. This principle encourages the church to actively pray for their ministers and those entering ministry, emphasizing that the effectiveness of the church depends on spiritually mature and converted leaders.
