Sorry, but this verse is talking about:
1. This world.
2. The world to come.
Anyone in either of those worlds who blasphemes the Holy Spirit will never be forgiven.
It is speaking either of the Old Covenant (this world) and the New Covenant (the world to come) or of the Present World (this world) and the Millennial Kingdom of God (world to come.)
Since the passage is already speaking of the Kingdom of God, this is the clear interpretation of scripture.
You better hope that the "world to come" is not DEATH.
Jesus promised ETERNAL LIFE.
I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. (Galatians 1:6-8 KJV)
