The most commonly taught view is that even in Christ, we still have sinful natures.
This view has been assumed, but not thoroughly examined.
Let’s look to the Scripture.
Which one of these two statements is scriptural? God is Spirit or God is Nature?
“God is a spirit: and they who worship Him must worship Him in spirit and in truth.” John 4:24
The lowest common denominator of Whom God is (and of man and angels), is spirit.
What is a nature then? A nature is a description of its underlying spirit.
And the underlying spirit of the sinful nature is the spirit inherited from Adam.
It looks like adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, sedition, heresies, envy, murders, drunkenness, reveling” Galatians 5:19-21
What is the nature of God?
“… that you might be sharers of the divine nature ….” 2 Peter 1:4b
He Is and shows Himself in love, joy, peace, patience, kindness, gentleness, faithfulness, and self-control (Galatians 5:22).
In salvation, we are put into Christ and He into us.
“… He has chosen us in Him before the foundation of the world, that we should be holy and blameless before Him in love:” Ephesians 1:4
“Put on the new person, who is created after God in righteousness and true holiness.” Ephesians 4:24
“Therefore if any person is in Christ, he is a new creature: old things have passed away; behold, all things have become new.” 2 Corinthians 5:17
In Adam, we inherited the baseline sinful spirit.
Through salvation in Christ, the last Adam, we are new selves sharing His divine nature.
“He who is joined to the Lord is one spirit with Him.” 1 Corinthians 6:17
Here’s an illustration of what becomes true of us in Christ at salvation.
