In Matthew 6 Jesus presents a template for how his disciples ought to pray. This sample prayer suggests several different requests that God asks us to make of Him.
Every Christmas the Rodgers family draws names from a hat to decide who will buy presents for whom. Each person is then responsible for providing a wish list to the person who will buy them gifts. Some people are more fun to shop for than others. Some gifts are fun to buy, as well as fun to get. The more fun your gift is to get, the more likely you are to get exactly what you want.
The blessings that Jesus suggests that we ask for are things that not only do we need, but God also wants to give us: provisions, forgiveness, righteousness. The secret to getting everything you could ever want is to want what God is wishing to give you.
