'When Christians let fall their heavenly expectations but heighten their earthly desires, they are preparing themselves for fear and trouble. Who has met with a distressed, complaining soul, where either a low expectation of heavenly blessings, or too high a hope for joy on earth is not present? What keeps us under trouble is either we do not expect what God has promised, or we expect what He did not promise. We are grieved at crosses, losses, wrongs of enemies, unkind dealings of our friends, sickness, or contempt and scorn in the world. But who encouraged you to expect any better? Was it prosperity, riches, credit, friends that God called for you to believe? Do you have any promises for these things in His Word? If you make a promise to yourself, and then your own promise deceives you, whom should you blame for that? We have less comfort in earthly things because we have too high and expectation from them. Alas, when will we learn from Scripture and providence to seek far more from God, and far less from the earth?'
Richard Baxter, Practical Works, II: 884-885
