How do we know prayer matters in the Christian life?

Prayer is of utmost importance in the life of a believer as it serves as the primary means of communicating with God. The Lord Jesus Christ exemplified the vital role of prayer during His earthly ministry, often retreating to pray and intercede for others. This practice shows that prayer is not only a way to bring our requests before God but also a demonstration of our dependence on Him. Moreover, prayer aligns our hearts with God's will, allowing us to approach Him confidently, knowing that He hears our cries and knows our needs. In Christ's high priestly prayer, for instance, He interceded for His followers, emphasizing the seriousness with which He approached prayer.
