2 Timothy 3:14-15

But as for you, continue in the things that you have learned and of which you are convinced [holding tightly to the truths], knowing from whom you learned them, and how from childhood you have known the sacred writings (Hebrew Scriptures) which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus [surrendering your entire self to Him and having absolute confidence in His wisdom, power and goodness].
