On one of his seven trips from Britain to America, George Whitefield was battling depression and feelings of failure and was stabilized finally only with meditation on God's love in Jesus Christ:
Nothing could possibly support my soul under the many agonies which oppressed me when on board, but a consideration of the freeness, eternity and unchangeableness of God's love to me.
I need not fear the sight of sin when I have a perfect, everlasting righteousness wrought out for me by . . . Jesus Christ. The riches of His free grace cause me daily to triumph over all the temptations of the wicked one. . . .
May he enlighten me more and more to know and feel the mystery of his electing, soul-transforming love. Nothing like that, to support us under present and all the various future trials. . . . But the Lord has apprehended us and will not let us go. Men and devils may do their worst; our Jesus will allow nothing to pluck us out of His Almighty hands.
