The Bible does not speak about becoming a different version of yourself. Nor does it teach about becoming a better version of yourself.

It speaks of becoming a new creation. The old self must die, and a new identity must be formed in the image of Jesus Christ.

Never think that you will be fit for heaven simply by becoming a polished version of yourself, or that a few minor modifications here and there will somehow qualify you for heaven.

The person born in the Adamic nature must die. Afterward, a new person must be born -one who bears no resemblance to the old self, but instead reflects the image of Christ.

This is what God demands. This is true Christianity: not a better version of yourself, but a new creation.
