Then Jesus said, "Come to Me, all of you who are weary and carry heavy burdens, and I will give you rest." (Matthew 11:28)
The effect, then, of all spiritual labor is to bring us to this point: to be weary of the world, for we feel it, for the most part, to be a valley of tears; to be weary of self, for it is our greatest plague; weary of professors, for we cannot see in them the grace of God, which alone we prize and value; weary of the profane, for their ungodly conversation only hurts our minds; weary of our bodies, for they are often full of sickness and pain, and always clogs to our soul; and weary of life, for we see the emptiness of those things which to most people make life so agreeable.
By this painful experience we come to this point: to be worn out and wearied; and there we must come, before we can rest entirely on Christ.
As long as we can rest in the world, we shall rest in it. As long as the things of time and sense can gratify us, we shall be gratified in them. As long as we can find anything pleasing in self, we shall be pleased with it. As long as anything visible and tangible can satisfy us, we shall be satisfied with them.
But when we get weary of all things visible, tangible, and sensible--weary of ourselves, and of all things here below--then we want to rest upon Christ, and Christ alone.
— J.C. Philpot, "The Laborer's Rest"
