I know that Christ is in me, and I in Him; but I ought not to be satisfied without the consciousness of enjoying Him. “That Christ may dwell in your hearts” is a prayer as to state, not a declaration of standing. What we have to watch is, not to unsettle the truth of the standing, but to apply the blessedness of the standing to the judgment of the state.
Thus, if you say you have fellowship with the Father and the Son, I say, Come, let us see. I saw you laughing just now at foolishness in the street: Is not that having fellowship with a fool? Thus it is, one applies the standing to judge the state.
When the standing is known, it is but the beginning of Christian life. If I am saved, I am inside the door; but inside, I want to know something of what is within. First, let the soul be grounded in that which is the substance of the whole truth. Then, if a person is not kept in a state corresponding to the standing, he may do worse even than the unbeliever.
