From an infant thou hast known the holy scriptures — Of the Old Testament. These only were extant when Timothy was an infant. Which are able to make thee wise unto salvation, through faith in the Messiah that was to come. How much more are the Old and New Testament together able, in God's hand, to make us more abundantly wise unto salvation! Even such a measure of present salvation as was not known before Jesus was glorified.
