Finally then, brothers, we beg and exhort you in the Lord Jesus, that as you received from us how you ought to walk and to please God, that you abound more and more.
so ye would abound more and more: One can never graduate from the school of Christ. Nor can one become so adept at living the Christian life that there is no further room for improvement. Neither is it possible for one to expend so much energy in Christian living that one can claim to have really done one’s best. There is always something more to learn, to be, to do; hence, Paul’s admonition to "abound more and more."
