1 Timothy 4:13-16

Until I come, give attention to the public reading of Scripture, to exhortation and teaching. Do not neglect the spiritual gift within you, which was bestowed on you through prophetic utterance with the laying on of hands by the presbytery. Take pains with these things; be absorbed in them, so that your progress will be evident to all. Pay close attention to yourself and to your teaching; persevere in these things, for as you do this you will ensure salvation both for yourself and for those who hear you.
