In my experience, the surest way to get a blessing is to be a blessing.

Deuteronomy 28:1-6 says, “If you listen obediently to the Voice of God, your God, and heartily obey all his commandments that I command you today,God, your God, will place you on high, high above all the nations of the world. All these blessings will come down on you and spread out beyond you because you have responded to the Voice of God, your God:

God’s blessing inside the city,
God’s blessing in the country;
God’s blessing on your children,
the crops of your land,
the young of your livestock,
the calves of your herds,
the lambs of your flocks.
God’s blessing on your basket and bread bowl;
God’s blessing in your coming in,
God’s blessing in your going out.”
