Jesus' mission in the first advent was to be the perfect sacrifice for our sins for all time for any who would would believe and repent. His mission in the second advent will be to conquer and overthrow.
Matt 24:14
14 And this
gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
How many Christians actually understand what this means? Christ is coming back, and it won't be like when he came the first time.
Heb 10:30
30 For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.
