Inner strength comes not from stoic endurance or even heroic resistance, but from doing what God means us to do in life, despite fear, doubt, an even death. The kind of inner strength that stands the test, even when we wish we were not tested, is best described by Saint Paul in Romans 8: For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
