Behind every good biblical preacher is much hard labor in preparation (1 Tim 5:17; 2 Tim 2:15). However, only prayer can assure that his work is not wasted and that his message will spiritually impact the hearers. As the biblical preacher interweaves prayer with his preparation, he should focus on certain petitions: 1. That he will receive God's message…in spiritual as well as mental comprehension (1 Cor. 2:9-16). 2. That God's message will first grip his own heart in strong conviction (1 Thes. 1:5). 3. That he will clearly and correctly convey God's message in the power of the Spirit in effective communication (1 Thes. 1:5). 4. That the Spirit will use the message to produce proper response and change, spiritual transformation (2 Cor. 3:18). 5. That the whole process and finished product will accomplish God’s purpose in glorification of God through Christ (1 Cor. 10:31; 1 Pet 4:11) (Henry Holloman).
