Hebrews 6:1-3

Therefore let us get past the elementary stage in the teachings about the Christ, advancing on to maturity and perfection and spiritual completeness, [doing this] without laying again a foundation of repentance from dead works and of faith toward God, of teaching about washings (ritual purifications), the laying on of hands, the resurrection of the dead, and eternal judgment. [These are all important matters in which you should have been proficient long ago.] And we will do this [that is, proceed to maturity], if God permits.
