The Lord says, “Don’t harden your hearts as Israel did at Meribah,
    as they did at Massah in the wilderness.
Psalm 95:8 (NLT)

We all know the basics of cardiac health. A healthy heart depends on what you consume and exercise. I have found that the same parallel pertains to the spiritual heart. Our spiritual hearts can get just as easily gummed up with the plaque of anger, hatred, negativity, doubt, fear, or anxiety.

To avoid the hardening of our spiritual arteries, we need to regulate what thoughts, messages, books, stories, posts, images, audio and videos we feed to our heart and brain. We also need to regularly engage our spirits in the conscious exercise of gratitude, generosity, kindness, forgiveness, goodness, and grace. A little strength training of prayer and worship helps, too.

Health is not only about our physical condition, but also about the conditioning of our hearts and minds.
