God/Bible in Romans 8.28: confirms, convinces and comforts the believers in Him; when we lose things; not to worry but to learn lessons and to trust in God; when we win to celebrate and to thank God. Every single moment we keep winning and losing, as we try to live our life. Nothing is loss to a Godly person. God teaches us by the loss we suffer and God rewards us by success we gain. In both ends; we can be receivers, if we reason and realize. So don't lose heart; rather cheer up and be watchful to win the next time. Forget the loss but not the lessons...
