Since God has given us memory and foresight, it is our duty to look ahead and provide as best we can for the future.

But having used these God given faculties in a sensible way, we are to be perfectly content having done our very best and all that is in our power, and knowing that God will look after the rest.

What you can do, is what you have done.

What you can't do is taken care of by the Providence of God.
