Negativity is just a result of thoughts existing out of God’s Will. 2 Cor. 10:5 says to take every thought captive to Christ. That means literally transferring every thought that whispers ‘you can’t do that,’ or ‘I wish I was her,’ or ‘ I’ll never get this right,’ and handing it over to the Lord. It can be tough, especially negative thinking seems justified, by the world’s standard, but positivity is a mental exercise that trains your heart and your brain to see things through God’s eyes.
If we focus on God, His goodness, His love and faithfulness, we can see past our negative thoughts. If you feel like you have greater chances of discovering life on Mars than losing that last 10 pounds, focus on the fact that you’re healthy and have the ability to exercise and move, when so many don’t. If your co-worker almost insists on slacking, or just plain drives you nuts, try praying for them, asking for grace, and be thankful you don’t share their same weaknesses. Like any spiritual exercise, it takes some practice, but it helps to think, “How would Jesus think and act in this situation? Even if we’d be right, in the natural, to feel and act negatively, God calls us to let go and think differently. With a willing spirit, nothing is impossible with Him.
