The Things Which Shall Be Hereafter by Septimus Sears.
The author writes "Soon after I tasted something of the preciousness of Jesus, I saw, but in a very dim way, that the present dispensation would give way to a future and glorious one, during which Jesus would personally reign with His saints; but having then but little learned to answer correctly the question of Eliphaz, 'To which of the saints wilt thou turn?' and meeting in print with remarks from some experimental Christians against the study of unfulfilled prophecy, I endeavoured to turn my mind from this subject; besides which, I became so fearfully exercised about my own interest in the blessings of the covenant of grace, that I felt this branch of truth lay very far from me while in a doubting position of soul.
That which lay nearest my heart was the making of my own calling and election sure; but, after frequent minor helps towards clearing my election, the Lord at length very mercifully gave me to realise that I was scaled by the Holy Spirit of promise unto the day of redemption. From that memorable period, when, with indescribable softness and gratitude of heart, I could say, 'O my Jesus, Thou art mine, with all Thy grace and power. I am now, and shall be Thine when time shall be no more.'"
