Prayer is an important ministry that benefits both God and others. It allows us to praise and serve God as our High Priest. Prayer is also how we ask God for help in times of need and bring our requests to Him with thanksgiving. Additionally, prayer is a ministry for others as we can pray on their behalf and access God's power through prayer to do good for others. The document provides guidelines for an effective prayer life, suggesting that prayer should be purposeful, reaching out to God, abiding with God continually, and yielding ourselves to God's will.
