2 Corinthians 5:17 ESV – Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.
Have you ever thought about the difference between fermentation and rot? Both are the process of decay but they have a different outcome. When something rots it might be used as fertilizer but for little else. When something ferments it becomes transformed into something other than what it was before.
In the fermentation process microorganisms, such as yeast, break down food components and the substance begins to change. Some familiar products of fermentation are yoghurt, cottage cheese, vinegar and sauerkraut.
The Holy Spirit is the yeast of our lives, causing us to become transformed. We are different after the transformation, infused by the Holy Spirit and a resident of Christ’s Kingdom.
