“God uses suffering to purge sin from our lives, strengthen our commitment to Him, force us to depend on grace, bind us together with other believers, produce discernment, foster sensitivity, discipline our minds, spend our time wisely, stretch our hope, cause us to know Christ better, make us long for truth, lead us to repentance of sin, teach us to give thanks in time of sorrow, increase faith, and strengthen character.”
