Hebrews 4:12 .. . . to whom is it written? It was written to the Jews who had intellectually agreed to the gospel, the facts about Jesus, the authority and power of the 1st century church, but were not converted. They had not come to the faith. It is written or built around a set of warnings, hence, the multiple use of the word "Beware". It also shows a new and better way, a complete way.
Chapter 1 . . . .
1In the past God spoke to our forefathers through the prophets at many times and in various ways, 2but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. 3The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
With just a quick glance of verse 12 the one thing that jumps out is the severity of it. . . . hence the words sharp, powerful, dividing, critic, piercing, and sword. Not a cuddly "love ya, how to" verse. It is a warning to the hearers that their emphasis was distorted. Look at the next verse. . . . . it ends with to whom we must give account. It is speaking about Jesus.
Who does scripture tell us is the living word? That is the question you can't guess on, hint, it wasn't Guttenberg. Remember, the whole context of Hebrews is Christ.
These are the people who were following the path of their forefathers . . . . when it refers to the children of Israel . . . those from the exodus . . . it referring to those who never entered the promise land. In Hebrews it is called entering into God's rest. They were never going to enter or be saved unless they started looking to Christ. He is the fulfillment of all God was trying to show them. He is the High Priest.
By trusting in their lineage, and their ceremonies and their ability. . their work's based sacrifice. . . .and themselves they were DENYING God's complete sacrifice and the only one He will accept.
The rest of Hebrews goes on to contrast the better way of Jesus vs their insistence on keeping their own rules.
1. Jesus is the living word
2. Jesus is the primary way God communicated to us. John 14:6
Hebrews is about missing salvation and it keeps pointing people back to the same thing every chapter. . . . Jesus Christ the same, yesterday, today, and forever. It is telling us NOT to rely on our own ability to direct, discern, and critique our own hearts. . . . it is saying put your faith in Jesus.
13 chapters of Jesus being the ONLY way . . . . and we still think we can train our hearts and exercise such great discernment?
The only thing our attention is directed to in Hebrews is Jesus Christ. Yes, a person, but it is not ourselves.
