2 Timothy 3:14-18

You, however, continue in the things you have learned and become convinced of, knowing from whom you have learned them,

and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus.

All Scripture is inspired by God and beneficial for teaching, for rebuke, for correction, for training in righteousness;

so that the man or woman of God may be fully capable, equipped for every good work.
