2 Corinthians 5:17 “Therefore, if any one is in Christ, he is a new creation; the old has gone, the new has come!”
The word in means within the shape of something or surrounded by something. Water in a bottle takes its shape from the bottle. Water has no shape but only takes its shape from the containers they are in.
So when a person claims to be in Christ and that he or she is a new creation, we are to take the image and shape which is the nature of Christ Jesus.
We can not claim one and do another. Water in a coke bottle can not take the shape of a malt bottle. If we claim to be
in Christ, then lets walk our talk. God bless you.
