Competitiveness is not defined as "loving to win and hating to lose". If that were the definition then everyone on the planet would be viewed as competitive as I have never found anyone who doesn't prefer winning over losing. However, competitive people don't merely love winning or hate losing. Competitive people "hate losing more than they enjoy winning". In other words, the feeling of loss hurts more than the joy of winning. God has a solution to this deep feeling of loss ... rejoice in the Lord and you will never lose because your strength comes from Him and not your own accomplishments.
Lord, thank you for providing solutions to my problems.
