when I know that he whom I have rested in hath power and grace enough to complete that which he hath begun in me, and for me; when I see the work of Christ to be no half-way redemption, but a complete and eternal salvation; when I perceive that the promises are established upon an unchangeable basis, and are yea and amen in Christ Jesus, ratified by oath and sealed by blood, then my soul hath perfect contentment. It is true, that looking forward there may be seen long avenues of tribulation, but the glory is at the end of them; battles may be foreseen, and woe unto the man who does not expect them, but the eye of faith perceives the crown of victory. Deep waters are mapped upon our journey, but faith can see Jehovah fording these rivers with us, and she anticipates the day when we shall ascend the banks of the hither shore and enter into Jehovah’s rest.
— The Joy of the Lord, the Strength of His People, C.H. Spurgeon
