While I am going, occupy yourself with reading, exhortation and teaching. 14 Do not neglect the gift that is in you, which was given to you through prophecy with the laying on of the hands of the presbytery. 15 Take care of these things; abide in them, so that your advantage may be manifest to all. 16 Take care of yourself and of doctrine; persist in it, for by doing this you will save yourself and those who hear you.
1 Timothy 4:13-16
14 You are the light of the world; A city set on a mountain cannot be hidden. 15 Nor do you light a light and put it under a bushel, but on the lampstand, and it gives light to all who are in the house.
Matthew 5:14-15
