Excerpt from a Letter to Lady Kenmure--February 1, 1630
I have neither tongue nor pen to express to you the happiness of such as are in Christ. When ye have sold all that ye have, and bought the field wherein this pearl is, ye will think it no bad market; for if ye be in Him, all His is yours, and ye are in Him; therefore, 'because He liveth, ye shall live also' (John 14.19). 'Father, I will that those whom Thou hast given Me be with Me when I am, to behold My glory that Thou hath given me' (John 17.24). Amen, dear Jesus, let it be according to that word. I wonder that ever your heart should be cast down, if ye believe this truth. I and they are not worthy at Jesus Christ, who will not suffer forty years trouble for Him, since they have such glorious promises. But we fools believe those promises as the man that read Plato's writings concerning the immortality of the soul: so long as the book was in his hand he believed all was true, and that the soul could not die; but so soon as he laid by the book, he began to imagine that the soul is but a smoke or airy vapor, that perisheth with the expiring of the breath. So we at starts do assent to the sweet and precious promises; but, laying aside God's book, we begin to call all in question. It is faith indeed to believe without a pledge, and to hold the heart constant at this work; and when we doubt, to run to the Law and to the Testimony, and stay there. Madam, hold you here: here is your Father's testament -- read it; in it He hath left you remission of sins and life everlasting. If all that you have in this world be crosses and troubles, down-castings, frequent desertions and departures of the Lord, still He purposeth to do you good at your latter end, and to give you rest from the days of adversity.
