2 Peter 1:4
By which he has granted to us his precious and very great promises — the promises function as both covenant expressions and transformative power sources. So that through these you may become partakers of the divine nature (theias koinōnoi physeōs) — perhaps the New Testament's boldest statement of theosis or deification, not pantheistic absorption but genuine participation in God's character. Having escaped from the corruption that is in the world because of sinful desire — the mechanism of spiritual transformation involves both positive participation and negative separation from worldly decay.
