Do you ever have them moments where you feel somethings not right? I have physically and spiritually. These are the times that you can either learn form it or hurt from it. If we don't stay tuned into our bodies and souls we can get off balance. With my husband he kept ignoring warning signs that something just wasn't quite right. After 4 times of going to the hospital they told him dehydration was the cause. If we don't get enough water in our system it starts acting weird. Just like our spirits if we don't have spiritual food (the bible) in our lives we get week. We might get depressed, do what we shouldn't, and so forth.
Proverbs 4:23 Keep thy heart with all diligence; for out of it are the issues of life.
