Rapture theology is the worst, imo. It tells you to EXPECT the church to fail to evangelize the world and that few people will believe in Christ in the end, that the church will utterly FAIL to fulfill the Great Commission, and the best thing you can do is hunker down and wait for Jesus to come and get you out of this mess. We Calvinists like to boast that Calvinism GAVE us modern missions and that it has done more in the last two hundred years to fulfill the Great Commission than anything else ever hoped to accomplish. And that's true- kind of. But I think what you find moving William Carey and the like forward to take the world for Christ is not their soteriology as much as their eschatology. They believed the church was going to do what Jesus said it would do- grow until it filled the earth. And they wanted to be a part of it. Even rabid Arminians like Finney and the Wesley's embraced this optimistic eschatology. I believe this is what we need today. I pray for the death of rapture theology in my life time and for a rebirth of earth conquering eschatology like the great missionaries had.
