I read today that on the Cuban Island de Pinos there is a prison “so dark and remote that most of the world never even knew it existed. The huge circular cellblocks were built during the 1930s under Batista’s regime. When someone asked the dictator why he had built it so big, he replied, ‘Ah, don’t worry. Somebody will come along who will manage to fill it up.’ That somebody was Fidel Castro.” 
As I read that it dawned on me, God had the same general idea. He has built a huge home with many rooms in Heaven, and given us the charge to help Him fill it up!
The Bible says that Satan prowls around like a lion, looking for someone to devour (1 Peter 5:6-11). It also says that God roams the earth, searching “to strengthen those whose hearts are fully committed to him” (2 Chronicles 16:9). God is looking for people to bless; Satan is looking for people to devour. Both are searching…who will you be found by?! Both are building “homes” with an abundance of rooms, waiting on someone to fill them. Whose home will you be in? And whose home are you helping to populate?
As horrific as it is that Batista built a prison in full confidence that someone (some future leader) would find a way to fill it up, I’m also a bit inspired by his vision. It’s like Field of Dreams – “If you build it, they will come.” What are we building for the future? God is building a mansion for us – that encourages me! I guess some of us have the job of building, others of filling…but in either case, may we be working in partnership with the Lord and with the confidence of Batista that someday those rooms God is preparing will be full—full with loved ones, full with those whose hearts we thought might be too hard and too far gone for God to reach, full with the nations, full with every tongue and every tribe.
