How does Christ's sacrifice relate to our prayers being heard?

Christ's sacrifice is central to the assurance that our prayers are heard. Because He bore our sins and troubles, we are granted access to the Father. Psalm 20 illustrates that it is through Christ that we can cry out to God with the certainty that He will respond. This access is emphasized in Hebrews 4:14-16, which encourages believers to approach the throne of grace with confidence, knowing we find mercy and grace in times of need. The reality of Christ's work transforms our prayer life from a routine task into a powerful lifeline to God.
