Why is Christ's intercessory role important for believers?

In Revelation, Christ's intercessory role is depicted through the altar of incense, representing prayer rising before God with the merits of His sacrifice. This highlights that believers have an advocate in Jesus, who mediates between us and the Father. In 1 John 2:1-2, it is noted that our advocate intercedes for our sins which assures us that when we approach God, we come through Christ's righteousness, not our own. This position gives us confidence that despite our failures, we are accepted through Him. Furthermore, this role illustrates the depth of our dependence on Christ for salvation, emphasizing that we cannot attain righteousness by our efforts alone.
