In Galatians, Paul exhorts us to not give way to weariness, and the way we are to do this is by keeping our eyes on the agricultural metaphor. We will not grow weary if we keep our eyes on the harvest. Good works, done for all men, but especially for the household of faith, are a form of farming. Plowing hard ground can seem like an eternal distance from the ripening grain of autumn, so lookahead. Consider the whole point.
