What you 'let' control your heart will be revealed in your words, actions and reactions. You either have control of it or it will control you. What is 'IT'? Negativity, harshness, bitterness, unforgiveness, hatred OR gentleness, kindness, humility, forgiveness, love.
As Christians, we should maintain the softness and flexibility of our hearts. We don't live in a perfect world so don't expect a life without flaws and mistakes. Matthew 7;2 ''For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.''
Some have said that because of my physical struggles that I could complain and be bitter but that's not the kind of example and reflection I want to be. My goal is to be a light to the world with no shadow of darkness. This won't be achieved until heaven, but it's worth striving for. Are you striving for it too?
