The blessing of the LORD brings wealth, and he adds no trouble to it (Proverbs 10:22).
Sometimes I act as if the LORD is a Buddhist or a Taoist or something. As if He's somehow concerned with karma or "universal balance." And while there is some element of (biblically-supportable) truth in some of these ancient Eastern philosophies -- it's important for me to remember that the LORD is a God of grace and faith, not karma or chi. He is the sovereign ruler of all the universe, which He created, and as such He may have grace on whom he chooses to have grace (Romans 9:18). He may bless whomever he wishes to bless, without having to give us an explanation or "even things out" somewhere along the line, as if we were children clamoring over the last piece of cake. This is a significant thing to remember from Proverbs 10:22.
So often, I can fear God's blessing in my life because I worry that I'll have to "pay for it" later. There's this underlying sense of believing that lightning never strikes twice. If it goes badly this time around, just wait and it will get better next time. Or if it's going well for me at the moment, watch out: something is going to happen to equalize everything. When I really stop and think about this philosophy, though, I realize that it's all superstition, really. All evidence to support such theories is anecdotal and circumstantial. It's not necessarily biblical. Because here we have it, as clear as day: The blessing of the LORD brings wealth, and he adds no trouble to it.
Ultimately, God is characterized by grace. He gives good gifts (most notably: salvation and everlasting life) to those who ask for it and who receive it with gladness. There's no sense of entitlement or privilege; we're all equally imperfect people who are saved purely by grace and faith. But if (and when) we experience God's blessing, we don't have to wait for the other shoe to drop, the yang to catch up with the yin, the feng shui of life to kick in. On the contrary, we can simply thank God and enjoy it for His glory. No strings attached.
