2. Since we are saved by grace, does what we eat and drink matter to God?

Definitely. The Bible says, “Therefore, whether you eat or drink, or whatever you do, do all to the glory of God” (1 Corinthians 10:31). To be clear, we are not saved by our dietary choices. It is a choice given us by God to honor Him. The choice to be temperate is twofold: 1. God is perfectly temperate, and a Christian should seek to be like Him, 2. Our bodies are the temples, or dwelling places, of the Holy Spirit; therefore, we seek to keep our body and mind as healthy and strong as possible. JTL19 4.1
