Hebrews 4:3

It is faith that opens heaven; but faith animated by charity, nourished by good works, and perfected by mortification of the senses. God only enters into his rest after the accomplishment of his works, and shall we expect to enter before we accomplish what he has given us to do? Let us fear, but in hoping; let us hope, but in labouring. --- The works....were finished. [1] This place is the same, and equally obscure in the Greek as in the Latin text. The apostle here examines what David, as a prophet, could mean, when he said of some: they shall not enter, or, if they shall enter into my rest. His argument is this: David could not prophesy of that rest, by which God, after he had created all things, (Genesis ii. 2.) is said to have rested the seventh day, when he had finished the works of creation. Nor could David speak of that other time of resting, which was promised and given to the Israelites, when, having conquered all their enemies, they were introduced by Jesus, or Josue [Joshua], into the promised land of Chanaan [Canaan]; for these two rests were passed long before his prophesy: therefore David must speak of some rest that was to come afterwards, when he said: To-day, if you shall hear his voice, harden not your hearts, &c. Therefore it must needs follow that some day of rest, some sabbatism, as he calls it, after his time, must remain for the people of God, that should not harden their hearts: and from hence he concludes that David had in view that eternal rest of happiness which the Messias was to obtain for us, a rest without end in the kingdom of heaven. --- Let us hasten, therefore, or as it is in the Greek, let us make it our endeavour, to gain that place of rest, by our persevering in faith and good works, and take heed not to be excluded with the unbelievers.
