'Ripe' in the Bible

Yet we do speak wisdom among those spiritually mature [believers who have teachable hearts and a greater understanding]; but [it is a higher] wisdom not [the wisdom] of this present age nor of the rulers and leaders of this age, who are passing away;

Brethren, do not prove yourselves to be children in your minds. As regards evil, indeed, be utter babes, but as regards your minds prove yourselves to be men of ripe years.
