Premillennialism is the doctrinal system teaching that this age will end with the physical return of Jesus Christ to the earth when He sets up a kingdom that will continue for one thousand years. The belief in the thousand year reign comes from a literal acceptance of Revelation 20:1-10.
Shortly before He drew His last breath, Jesus Christ cried out, “It is Finished”. At that place and time He bore our sins in His body on the tree, became a curse for us and paid the debt for our sins. On the cross He completed all of the physical and spiritual sufferings needed for the salvation of mankind.
Now let us consider what is most properly called Spirit baptism. The Bible does not talk as much about this one. However, it is a Bible doctrine. At the point of salvation the Holy Spirit places us into Jesus Christ. When a soul trusts in Christ and is saved, he or she is “in Christ.”
