Charles H. Spurgeon on Psalms 27:13

Faintness of heart is a common infirmity; even he who slew Goliath was subject to its attacks. Faith puts its bottle of cordial to the lip of the soul, and so prevents fainting. Hope is heaven's balm for present sorrow. In this land of the dying, it is our blessedness to be looking and longing for our fair portion in the land of the living, whence the goodness of God has banished the wickedness of man, and where holy spirits charm with their society those persecuted saints who were vilified and despised among men. We must believe to see, not see to believe; we must wait the appointed time, and stay our soul's hunger with foretastes of the Lord's eternal goodness which shall soon be our feast and our song.
