Read Colossians 1:16.
God, the Creator, owns everything, including each of us. When we invest our faith in Him, and do His works, we are giving back to our Creator. I often wonder if God looks at me the way I look at my IRA. There are ups and downs daily depending on the market. But you cannot get short sighted. You have to look at the market, and your life, for the long term. Every day you are growing, adding value, and reinvesting dividends in yourself – like an IRA. So regardless of where you are at any one point today, or this week, or even this month – long term you are on a steady incline of value, doing works for God. YOU are His IRA fund for the future. YOU are here working on Earth for Him. Don’t give up when there is a dip in the market, hold steady.
