F.B. Meyer emphasizes the importance of supporting traveling evangelists for the sake of the Name of Jesus, urging believers to provide hospitality that reflects God's generosity and grace. He highlights the evangelists' pure motives, as they seek to glorify Christ without seeking support from those who do not share their faith. Meyer encourages the church to welcome such servants of God, reminding them that by doing so, they become fellow-helpers in spreading the truth. The sermon calls for a selfless and gracious attitude in our interactions with both brethren and strangers.
