Phil. i. 23, 24. “For I am in a strait betwixt two, having a desire to depart and be with Christ which is far better; nevertheless to abide in the flesh is more needful for you.” To depart and be with Christ must, I conceive, mean in the resurrection world, for in no other sense could he be with Christ so as to render his condition “far better.” Nothing can be good or bad for a man in a state of perfect insensibility, any more than for a man unborn—Neither could he be with Christ in such a State, any more than before he existed. Between the condition of a man in non-existence [pardon the expression] and in life, no comparison as to enjoyment or suffering can possibly be drawn. The apostle therefore draws a comparison between his present condition of conscious existence with his brethren, and his future condition of conscious existence with Christ which was far better.
That Paul has reference, in the above, to an immortal existence in the resurrection, is evident from 2 Cor. v. 1, 2, 3, 4.
“For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, a house not made with hands eternal in the heavens. For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven. If so be that being clothed we shall not be found naked. For we that are in this tabernacle do groan, being burdened, not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.”
