A while back, I read a book which documented the stories of people who had won large lotteries. With just one exception (a Christian woman who tithed heavily and went on living the same as before), the recipients were worse off after winning than before. One had even been killed for his money. Most had lost friends. Others had quit their jobs or gone into such debt they were staring at poverty.
Wealth gotten quickly through any dishonest or corner-cutting means (exploitation and gambling come to mind) is not blessed in the end.
By comparison, Christ gained an imperishable inheritance for us by leaving his riches in heaven (2 Corinthians 8:9), living a perfect life (Hebrews 4:15) and finally dying an agonizing death in our behalf (1 Peter 1:3-6). From his life we see that a blessed inheritance is one gained by steady determination and self-sacrifice.
