1 Corinthians Chapter 15: Verses 1 - 2
Do not neglect your gift, which was given you through a prophetic message when the body of elders laid their hands on you.

Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.
1 Timothy Chapter 4: Verses 14 - 16
