For some communion is an every Sunday event. For others, it is not. Preparation can run the range from nothing at all to days of fasting and meditation. The apostle Paul might be suggesting that every day of the week might be the best preparation for partaking. Actually, he says our every day lives are living and holy sacrifices - true worship.
What better way to see Jesus in the elements of communion by see our lives as a worshipful extension of his life, death and resurrection.
Let's think about Romans 12:1-2 as we come to communion.
