Hebrews 6:1, (KJV)
"Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,"
Hebrews 6:1, (NLT)
"So let us stop going over the basic teachings about Christ again and again. Let us go on instead and become mature in our understanding. Surely we don't need to start again with the fundamental importance of repenting from evil deeds and placing our faith in God."
WHY DOES SPIRITUAL GROWTH MATTER SO MUCH?
Because his readers have not progressed beyond the gospel's fundamental truths, the author of Hebrews is concerned for them. Spiritually, they have not matured.
He has scolded them for their spiritual immaturity (Heb. 5:11-14). He wants to teach his readers about the solid food found in the fulfillment of the Melchizedek priesthood in Jesus Christ's life and activity. "Concerning Him we have much to say" is referring to both Melchizedek and Christ.
Some of his listeners, though, are "deafeningly deaf." Spiritually and mentally, they are sluggish. They have been in this situation for so long that they are unable to comprehend even the most basic Christian message. They should have grown spiritually mature enough to teach in the local church if they had actually been born again. Every Christian is required to be able to share and defend his or her testimony of God's rescuing grace. These readers are spiritual children who are unable to comprehend even the most fundamental spiritual truths.
The ABC's of Christianity, or the most basic knowledge of what it means to become a Christian, are discussed in the context of Hebrews 5 and 6. These people are unable to recognize God's righteousness at its most fundamental or basic level. God's revelation regarding every believer's righteousness is referred to as the "message of righteousness." It is a right relationship established by God's grace through faith in Jesus Christ.
No one can be rescued apart from His saving grace. Something is amiss if this does not result in a changed life. Through the word of righteousness, we grow in maturity. It's disgraceful that some of these people don't know what they're talking about when it comes to Christian teaching.
They've got plenty of opportunity to grow up. Some members of the church are of high spiritual awareness and are of full age. They have reached full maturity in God's unfathomable mysteries. This maturity is attained through combining faith with the promises of God's Word.
Let us be careful not to engage in eisegesis, or reading something into the Bible that isn't there.
