In an earlier post I spoke about capturing our thoughts in Christ and renewing our mind with the help of his grace. It's an ongoing battle. The shrew would like to put in her two cents about everything. I have to gag her to get her to shut up. The shrew likes to comment negatively on life in general, though she has mellowed with age. She was far more fierce in her younger years, I think she got burnt out. Still, she occasionally likes to butt her head into my thoughts :)
All humor aside, our thought life has a lot to do with who we are and how we treat others. Unhampered, it will run ourselves and others into the muck if we let it. We have the grace to stop our thoughts and change their direction by gently moving our thoughts toward the Lord. For instance, if we find ourselves judging a person [not an action, it is okay to judge an action] our thoughts can carry us far away from truth. No one knows another person's heart but God. When we notice our thoughts bringing us into a direction we don't like it's helpful to think of Jesus crucified. Takes the wind right out of our sails! Or say your thoughts about yourself are harmful [like cutting yourself down or digging into a painful past all the time] it's helpful to remember how much God loves you. I say do it gently because it needs to be done with love. You have to treat yourself with the same mercy that God treats you with. God is incredibly merciful to us and so, we too, must treat his creation lovingly. It takes many years to build up negative thought habits and it can take some time to change this. If you are too harsh with yourself - it is fighting negativity with negativity rather than the greater sword of God's love. Our greatest weapon is praise. Praising God leaves no room for the shrew :) I like to think of this not as positive thinking but rather....Christian thinking.
