John Nelson Darby emphasizes the importance of recognizing the current state of the church, which he describes as a general ruin of the dispensation. He expresses confidence in God's ability to maintain a remnant of believers united in love through the Holy Spirit, rather than relying on formal government structures. Darby believes that true ministry comes from the conscience in grace and that Christ's presence is assured where believers gather in His name. He warns against the dangers of seeking carnal unity through authority and encourages reliance on God's provision for the church's needs. Ultimately, he advocates for a humble approach to church life, trusting in God's faithfulness and the power of the Holy Spirit.
