It is impossible for any rational creature to be happy without acting all for God. God Himself could not make him happy any other way... There is nothing in the world worth living for but doing good and finishing God's work, doing the work that Christ did. I see nothing else in the world that can yield any satisfaction besides living to God, pleasing Him, and doing his whole will.
David BrainerdIf you hope for happiness in the world, hope for it from God, and not from the world.
David BrainerdFurther, Take heed that you faithfully perform the business you have to do in the world, from a regard to the commands of God; and not from an ambitious desire of being esteemed better than others.
David BrainerdOf late God has been pleased to keep my soul hungry almost continually, so that I have been filled with a kind of pleasing pain. When I really enjoy God, I feel my desires of Him the more insatiable and my thirstings after holiness more unquenchable.
David BrainerdThe whole world appears to me like a huge vacuum, a vast empty space, whence nothing desirable, or at least satisfactory, can possibly be derived; and I long daily to die more and more to it; even though I obtain not that comfort from spiritual things which I earnestly desire.
