2 Peter 1:3-4:

According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:
Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.

Notes on 2 Peter 1:3-4:

Does healing pertain to life and godliness?  I would say so!  If you don’t receive your healing, you can have a much shorter life, and certainly a less enjoyable life, and you won’t be as equipped to do works of godliness.  If healing were not provided, Peter could not say that God’s divine power has given you all things pertaining to life and godliness.

This is another passage like Ephesians 1:3 that shows you that everything you need has already been provided.  Therefore, you need to receive these things, including healing, rather than begging God for what you already have been granted.
