Advice to aspiring ministers: Get in the Word. Stay in the Word. Master the Word. And for heaven's sake, preach the Word!
Heaven is a place where God will personally wipe away our tears.
The rapture will not be secret but open and manifest. Its purpose will not be to whisk the elect away from the earth for a while until Christ returns for a 'second' Second Coming. The purpose of the rapture is to allow the saints to meet Jesus in the air as He returns and be included in His entourage during His triumphal descent from Heaven. His coming in this manner will be attended by the general resurrection, the final judgment, and the end of the world.
But the blessing Christ promised, the blessing of great reward, is a reward of grace. The blessing is promised even though it is not earned. Augustine said it this way: Our rewards in heaven are a result of God's crowning His own gifts.
The only way the kingdom of God is going to be manifest in this world before Christ comes is if we manifest it by the way we live as citizens of heaven and subjects of the King.
