Hopefully making theology simpler to understand! (2 Corinthians 1:12)

Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.

2 Corinthians 5:17, ESV

We are sinful, yet our God has made a way for us to be cleansed through the blood of Christ. When we are cleansed, we are spiritually made new, our mind being conformed to Christ’s, as we await Hos return and full physical renewal, as well.
