As a followup – don’t forget the 3 types of people:
Natural / Unsaved
Carnal Christians – saved, but not growing, looks like an unsaved person
Sprit-Filled Christian – growing, perhaps slowly, but growing, asking forgiveness of sin, praying, reading their Bibles, etc.
Again, what type are you?
Where do you want to be?
Will you ask God to help you move?
Also, what type are your friend?
Can you help them?
And don’t forget this: what type do whose who see you at school think you are? If you are a spirit-filled and yet people at school think you are unsaed, that’s not good.
