And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice—the kind he will find acceptable. This is truly the way to worship him.
Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect.
In the same way, some think one day is more holy than another day, while others think every day is alike. You should each be fully convinced that whichever day you choose is acceptable.
“Don’t you understand either?” he asked. “Can’t you see that the food you put into your body cannot defile you? Food doesn’t go into your heart, but only passes through the stomach and then goes into the sewer.” (By saying this, he declared that every kind of food is acceptable in God’s eyes.)
But when you pray, go away by yourself, shut the door behind you, and pray to your Father in private. Then your Father, who sees everything, will reward you.
