Does " be certain of your grace" mean " be certain being graced by you"?

Context:

If then I have grace in your eyes, let me see your ways, so that I may have knowledge of you and be certain of your grace; and my prayer is that you will keep in mind that this nation is your people.


Another version:

Now therefore, I pray thee, if I have found grace in thy sight, shew me now thy way, that I may know thee, that I may find grace in thy sight: and consider that this nation is thy people.

'Be certain being graced by you' is, unfortunately meaningless.

The writer of the prayer hopes to be certain of the grace of God (meaning 3).
