This is how the Heidelberg Catechism of 1576 answers that question:

Because I am a member of Christ by faith[1] and thus share in His anointing,[2] so that I may as prophet confess His Name,[3] as priest present myself a living sacrifice of thankfulness to Him,[4] and as king fight with a free and good conscience against sin and the devil in this life,[5] and hereafter reign with Him eternally over all creatures.[6]

[1] I Cor. 12:12-27. [2] Joel 2:28 (Acts 2:17); I John 2:27. [3] Matt. 10:32; Rom 10:9, 10; Heb. 13:15. [4] Rom. 12:1; I Pet. 2:5, 9. [5] Gal. 5:16, 17; Eph. 6:11; I Tim. 1:18, 19. [6] Matt. 25:34; II Tim. 2:12.

Now that’s an adequate answer!
