It is common for those who design to undermine any truth of God, to load it with difficulties. But we wrong ourselves, and wrong the truth of Christ, when we form our notions of the world of spirits by this world of sense.
There are more worlds than one; a present visible world, and a future unseen world; and let every one compare this world and that world, and give the preference in his thoughts and cares to that which deserves them.
Believers shall obtain the resurrection from the dead, that is the blessed resurrection. What shall be the happy state of the inhabitants of that world, we cannot express or conceive, 1Co 2:9. Those that are entered into the joy of their Lord, are entirely taken up therewith; when there is perfection of holiness there will be no occasion for preservatives from sin.
And when God called himself the God of these patriarchs, he meant that he was a God all-sufficient to them, Ge 17:1, their exceeding great Reward, Ge 15:1. He never did that for them in this world, which answered the full extent of his undertaking; therefore there must be another life, in which he will do that for them, which will completely fulfil the promise.
