In this sermon, the preacher tells the story of a blind man who had his eyes opened by Jesus. The blind man was fixated on the idea of someone being able to open the eyes of the blind, and when he heard that the Messiah would do this, he believed that Jesus was the Messiah. When Jesus called him, the blind man eagerly came to him without hesitation. Jesus asked the blind man what he wanted, and the man simply asked to be able to see. Once his eyes were opened, the blind man's only desire was to continue seeing Jesus and follow him. The preacher uses this story to encourage the listeners to come to Jesus and seek him with the same eagerness and single-mindedness as the blind man.

Andrew Murray emphasizes the necessity of definite prayer, illustrating how Jesus asked the blind man, 'What wilt thou that I should do unto thee?' to highlight the importance of articulating specific needs in prayer. He argues that vague prayers often lack the power to elicit a response from God, as they do not reflect a true understanding of one's desires or faith. Murray encourages believers to examine their hearts and express their requests clearly, as this not only strengthens their faith but also aligns their will with God's. He asserts that true prayer involves a commitment to seek God's will actively and to expect answers, fostering a deeper relationship with the Father. Ultimately, Murray calls for a prayer life that is both earnest and specific, leading to a more profound experience of God's grace and provision.
