Admonished not to degenerate from his ancestors

"Remove not the ancient landmark, which thy fathers have set."-Proverbs 22:28  

"Calling to remembrance that unfeigned faith Not so much for the purpose of applauding as of exhorting Timothy, the Apostle commends both his own faith and that of his grandmother and mother; for, when one has begun well and valiantly, the progress he has made should encourage him to advance, and domestic examples are powerful excitements to urge him forward. Accordingly, he sets before him his grandmother Lois and his mother Eunice by whom he had been educated from his infancy in such a manner that he might have sucked godliness along with his milk. By this godly education, therefore, Timothy is admonished not to degenerate from himself and from his ancestors."1-John Calvin
