At once

And Caleb stilled the people before Moses, and said, Let us go up at once, and possess it; for we are well able to overcome it. – Numbers 13:30

At once.

Immediately.

Without further delay.

As you are.

Now.

Right now.

You know what to do, and you are more than able to do it (especially if you feel inadequate for the task).

Go right now, as you are, and possess the land.
