F.B. Meyer emphasizes the transformative power of Christ working through individuals, as illustrated by Hudson Taylor's calling to evangelize inland China. He highlights that personal limitations do not hinder God's work, as it is Christ who empowers believers to fulfill their responsibilities. Meyer uses the analogy of a copper wire, which merely conveys the power of the battery, to illustrate how believers can be vessels for Christ's might. The message is clear: when we rely on Christ, we can accomplish great things despite our weaknesses.
