What does the Bible say about confidence in prayer?

1 John 5:13-15 emphasizes that our confidence in prayer is rooted in our relationship with the Lord Jesus Christ. John specifically states that we know we have eternal life and that this confidence is tied to our belief in His name. When we approach God in prayer, we must do so with the understanding that our requests should align with God's will. Confidence in prayer comes not only from faith in Christ but also from the reassurance that God hears us when we pray in accordance with His purpose.
