And how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. (NIV)

And how from your childhood you have had a knowledge of and been acquainted with the sacred Writings, which are able to instruct you and give you the understanding for salvation which comes through faith in Christ Jesus [through the leaning of the entire human personality on God in Christ Jesus in absolute trust and confidence in His power, wisdom, and goodness]. (AMP)

And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. (KJV)
