Why is the concept of intercession important in Christian theology?

Intercession is a key concept in Christian theology as it signifies Christ’s role as the mediator who continually advocates for believers before the Father. Hebrews 7:25 explains that 'He is able also to save them to the uttermost that come unto God by Him, seeing He ever liveth to make intercession for them.' This highlights that unlike the Levitical priests who served temporarily and were limited by death, Christ’s intercessory work is eternal, providing believers with assurance of His ongoing support. His ability to intercede is rooted in His perfect sacrificial work that reconciles us to God, emphasizing the relationship of grace that the new covenant provides.
