9 And having been perfected, He became the author of eternal salvation to all who obey Him, 10 called by God as High Priest “according to the order of Melchizedek,” 11 of whom we have much to say, and hard to explain, since you have become dull of hearing. (Hebrews 5:9–11, NKJV)
The great truth that Jesus Christ is the sinless sacrifice by whom our eternal salvation is offered is fundamental to the gospel of His grace. It is also basic truth that He saves “all who obey Him” – obedience faith is necessary to be saved and go to heaven (Ephesians 2:8-9). Christ’s appointment by God as the High Priest of our confession to serve in heaven of God’s house is crucial to our redemption (Hebrews 3:1; 8:1-2). Understanding the nature and work of our High Priest enlivens our hope and sustains our diligent service to Him. Yet, like the Hebrew Christians, we may not be in a good position to learn these things. We become “dull of hearing” (difficult to teach) if we are not diligent hearers and doers of the word (James 1:21-25). Spiritual growth in Christ requires a heart that is open to Christ’s word and a life that is using His word “to discern both good and evil” (Hebrews 5:14). How’s your hearing?
