In athletics, if you come up against a particular high hurdle that you have to jump, you take a longer run!
If you want to vault over it, you go further back. You do not try to lift yourself up over the high hurdle from which you are on the ground. The further back you go, the longer you run, and the momentum will carry you over.
That is a very valuable principle in the exposition of Scripture and the elucidation of some [of the] problem with which it presents us.
Dr. David Martyn Lloyd Jones, Romans 10: Saving Faith
