“Therefore, let us leave behind the basic teaching about Christ and advance to maturity, without laying the foundation all over again: repentance from dead works and faith in God, instruction about baptisms and laying on of hands, resurrection of the dead and eternal judgment” (Hebrews 6:1-2).
The author advises the Hebrews to spiritual growth. Christians must keep the principles of the Christian doctrine, as the foundation of all their profession and expectation, and then develop a Christian superstructure.
“But we are sure in your regard, beloved, of better things related to salvation, even though we speak in this way. For God is not unjust so as to overlook your work and the love you have demonstrated for his name by having served and continuing to serve the holy ones. We earnestly desire each of you to demonstrate the same eagerness for the fulfillment of hope until the end, so that you may not become sluggish, but imitators of those who, through faith and patience, are inheriting the promises” (Hebrews 6:9-12).
