Note, First, It is our duty and interest at all times, especially in perilous trying times, to secure the possession of our own souls; not only that they be not destroyed and lost for ever, but that they be not distempered now, nor our possession of them disturbed and interrupted. “Possess your souls, be your own men, keep up the authority and dominion of reason, and keep under the tumults of passion, that neither grief nor fear may tyrannize over you, nor turn you out of the possession and enjoyment of yourselves.” In difficult times, when we can keep possession of nothing else, then let us make that sure which may be made sure, and keep possession of our souls. Secondly, It is by patience, Christian patience, that we keep possession of our own souls. “In suffering times, set patience upon the guard for the preserving of your souls; by it keep your souls composed and in a good frame, and keep out all those impressions which would ruffle you and put you out of temper.”--Matthew Henry.
"Though you are surrounded on all sides with many miseries, yet nonetheless be valiant and courageous, and bear out these things bravely." -- the note from the Geneva Bible on Luke 21:19.
