I was thinking the other day about all the different things that people eat. What you put on your plate, look at with your eyes, and smell with your nose reflects what's in your heart and vice versa. I mean, what you eat affects your heart.
So likewise, eat Godly food, or at least...if you know it's bad for you...don't eat it! (For those who aren't aware, leafy greens, whole grains, and lean meats are acceptable; fatty meats, starchy vegetables, and Cheetos Puffs ARE NOT!
It could affect your relationship with God as it affects your heart (coronary disease, hypertension, etc.) or even your blessings from Him.
