Matter is everything around us; down to the smallest atom, up to the largest star and beyond. It’s defined as anything that has a physical existence: and that, of course, includes us too .
One well-known passage of scripture says that there’s an appointed time for every matter under heaven; another says that God created everything for a purpose. In some translations of the Bible, “matter” is replaced by “purpose”: which means that – like the billions of particles, elements, and other matter in the universe – each of us has a purpose too.
Simply put: if we exist, we matter, because He made us.
So live your purpose. It’s your time.
Romans 8:28, Ecclesiastes 3:1 (ESV, NKJV), Proverbs 16:4.
