Hebrews chapter 5: The author of Hebrews has not been remiss to remind the reader that even though they are facing persecution and difficulty in their lives they should beware of drifting and disbelief which is part of the disease of the deadly d’s.
Christ is supremely appointed as our high priest according to the order of Melchizedek. He is and was the perfect Lamb of God to take away the sin of the world. As the Son, Jesus is superior to angels, superior to Moses and now superior to Aaron. And yet in his humanity he suffered, prayed deeply, was tempted yet without sin. This is why he could “[become] the source of [our] eternal salvation.”
The next deadly d has to do with diet. The readers were still infants feeding upon milk, the basic principles of the gospel and not feeding upon the meat of the Word. They knew Jn 3:16 but not the greater implication. They were like the disciples who over and over asked: “what does he mean?” They should have been teachers but just want their ears tickled. Instead of hungering, thirsting and being trained to discern truth from error they were satisfied just being spectators leaving the study of the scriptures to others. We see them today in our churches. They come faithfully to service but do not attend classes for instruction and fellowship. They may have accepted the WORD but are not feeding upon the WORD.
We need to be asking if we too are failing. Do I hunger for the solid food of the Word? Can I discern truth from error? Am I obeying Matt 28: “go and make disciples?”
