2 Corinthians 5:17
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. NKJV

When I was dating Pr. Stephen, one of the things we used to do together was run businesses. We ran two businesses; a washing bay and a second-hand clothes mobile boutique.  We loved going down town to a place called Owino market to pick out what we thought were good deals.  At only UGX 50,000, we would come out with a sack of clothes to sell at a profit. It was so much fun that we did it for quite some time and bonded around it. During that time, I learned a lot about second-hand clothes. To start with; they can never be new no matter how much you washed and ironed them.  Secondly, they many times come with a damage which explains why they were disposed of in the first place which means they needed repair before you could sell them.  Sadly, sometimes you saw the damage after purchase so you could either repair the damage or forgot about the profit. Sometimes, no amount of repair could take away the damage. Second-hand clothes also got worn out quickly to mention but a few. There is a clear difference between second-hand clothes and brand-new clothes.  No matter what you do, the two are not the same. 

When you and I got born again, God did not take our former selves for repair, dry or wet wash, resize, ironing, name it. He did not improve the old us. He did away with the old and made each one of us a new creation. There was nothing about the old us that could be repaired.  We were already worn out by sin. We were beyond repair.  God through Christ had to create a brand-new person in you and I. If you are in Christ, you are brand new. The old is dead, all things about you have become NEW.  Therefore, you and I need to stop resurrecting what passed away to repair or improve it.  There’s no self-improvement plan that can change you and I completely and eternally like being in Christ. 

Today, if you are not yet born again, and you have been on a self-improvement/repair plan, I would like to urge you to forsake it and say yes to Christ. Through Him you will become brand new.

If you are already born again, but you are working hard to improve yourself to fit the new frame.  The honest truth is that you cannot.  The work has already been done through Christ, renew your mind to this truth and believe that you are not the former, you are not even an upgrade. You are a new creation by the grace of God.
