2 Pet 1:1
Simon Peter, a servant and an apostle of Jesus Christ, to them that have
obtained like precious faith with us
through the righteousness of God and our Saviour Jesus Christ:
Peter in this scripture does inform us where precious Faith comes from ! Its certainly not of ourselves
Eph 2:8.
It comes in or with the Righteousness of God and Our Saviour, this Righteousness is the
free gift that Christ purchased and bestows upon all for whom He died
Rom 5:17
For if by one man's offence death reigned by one; much more they
which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ)
This Righteousness as well as that referred to in
2 Pet 1:1 is the imparted Righteousness of Christ we receive at New Birth. It is through this imparted or communicated Righteousness at New Birth we receive of, that with it we are given precious Faith.
Peter goes on to say
2 Pet 1:3-4
3
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:
4 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.
Faith or precious Faith is of the many things Given to us by New Birth which gives us to live a life of godliness !
So
2 Pet 1:1 is but another scripture that proves biblically that Faith is the product of New Birth, partaking experimentally of the Divine Nature !
