What does it mean to approach God through Christ in prayer?

To approach God through Christ underscores the significance of having a mediator who pleads for us. As Ephesians 2:18 states, through Christ, we have access to the Father by one Spirit. This means that in prayer, we rely not on our own merits but on the righteousness of Christ. He intercedes for us as the perfect High Priest, assuring us that our petitions are heard by the Father because of His finished work. This is foundational in sovereign grace theology, where the believer's confidence in prayer rests upon Christ's sufficiency and role as mediator.
