By which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire. (2 Peter 1:4 )
We have been changed by his grace, are being changed by his grace, and will be changed his grace.
What is the goal of this change? It is more than a better marriage, well-adjusted children, professional success, or freedom from a few nagging sins. God’s goal is that we would actually become like him. He doesn’t just want you to escape the fires of hell—though we praise God that through Christ you can! His goal is to free us from our slavery to sin, our bondage to self, and our functional idolatry, so that we actually take on his character!
