Except you, in your personal exercise and experience, do know what this throne of grace is, and what is got there; you may be Christians hereafter, but as yet you are none; unless you experience what this throne of grace is, by frequent repairing to it, and by frequent receiving good at it. That man or woman, whatever his or her name be in the world, or the church of Christ, that never found any need for, or use of, or benefit by this throne of grace, is surely a dead sinner. People may safely and surely judge of both the state and frame of their souls, by their business at the throne of grace. Never got any soul life, but by an act of grace from this throne. No soul can be kept in life, but by daily intercourse with it. It is as impossible that these bodies of ours should be maintained in life and strength without meat, and drink, and air; as it is for the soul of a believer to prosper without daily plying the throne of grace.
