Problems, trials, and challenges can make us better—or worse.
How we respond to disappointments and setbacks will in many ways set the course of our lives and make us either bitter or better. Determine, by the grace of God, not to get discouraged and side-tracked by the difficulties of life. Make up your mind that you will follow Jesus—and trust Jesus—no matter what. Trust Him, and the Lord will use your troubles to make you stronger and sweeter.
Count it all joy, my brothers, when you meet trials of various kinds, for you know that the testing of your faith produces steadfastness. (James 1:2,3 ESV)
