John Wesley on 2 Chronicles 32:1

After, &c. - An emphatical preface, signifying, that notwithstanding all his zeal for God, God saw fit to exercise him with a sore trial. And God ordered it at this time, that he might have an opportunity of shewing himself strong, on the behalf of his returning people. It is possible, we may be in the way of our duty, and yet meet with trouble and danger. God permits this, for the trial of our confidence in him, and the manifestation of his care over us.
