Can the Lord bless a blind decision? (even a wrong one?)

I think this is what the Lord works with: When you recognize that He is in you, not that you are righteous or even obedient, but that He is here in Mercy. We earn nothing, but in an act of perfect Love, Jesus gives His Grace freely to those who would only believe.

He is here. He has always been here. He is faithful when you are not.
You cannot sin freely in Light of His Grace; the Lord will not be mocked. But through Humility, you are given a relationship with the Highest. With this understanding, you may be joyful in every circumstance, giving all requests to the Lord with thanksgiving! 1 Thes. 5:16

Where is fear to hide in this Light? If I bring a request to the Lord, and He does not answer, I will carry on in the knowledge that He knows what I need and is faithful.

His message may not be in what job I take now, but that He offers peace even in struggle. The act of faith is what He wants, for, “without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.” Hebrews 11:6
