Blessed are they that mourn, for they shall be comforted.
The next mark of a true disciple is godly sorrow, which maketh a man in all sort of grief to power out himself unto God in Christ, and to seek relief from him. Whosoever do follow after Christ, mourning in the sense of sin, or fear or wrath, however they may seem miserable in their own, or the worlds eyes, yet are they very blessed for of such Christ saith, Blessed are they that mourn. Such mourners may be destitute for a time of comfort, but at no time can they be destitute of blessedness, for even in the time when they are mourning, and do want comfort, it is said of them. They are blessed. Albeit their comfort be delayed for a time, yet it shall not always be withheld, for the word of consolation is here spoken unto them, which they in due time shall find applied, and verified unto them by God's Spirit; for it is said, They shall be comforted; and this shall be partly by being made to see satisfactory reasons of God's delaying to comfort them, partly by receiving now and then, real deliverance's and sensible outgates of their mournful condition; and partly by being supported with strength in the inner man, at all times, that they succumb not, till at last they be fully delivered for ever.. They shall be comforted, saith the Lord.
