Many people wonder if prayer matters when God already has a perfect plan. The story of Moses interceding for Israel in Exodus 32 reveals that prayer isn't about changing God's mind, but about participating in His purposes. God's plans are perfect and His purpose never changes, but He chooses to accomplish His will through our prayers. Prayer moves us from trying to control our circumstances to aligning our hearts with God's will. When we pray, we're not rewriting God's plan - we're stepping into it and finding our place in His perfect purposes.
