I do believe that many decisions - such as jobs - are not much concern of the Lord. He tells us not to worry about mundane things such as food and clothing nor to work at being rich. I think He reveals to us that our character being conformed to Christ is of utmost concern - for in that He is glorified and we are true to the One who bought us.
To the slave, be content. To the rich man, be not high minded. In all things, do unto the Lord and not your earthly master.
“Manage” your character (pursue Christ) and take the job you want. If greed is one’s motivation, the character of Christ will restrain, convict, re-direct, etc.
Most of us (I speak for myself) do not well at following the explicitly revealed will of God for us (1st Thessalonians 4:3-7 for example) - why would we expect Him to reveal beyond His Word in such a situation? He who is faithful in little things will be given more.
I have found that when I am faithful to the “little things” that He has revealed to me, the “bigger things” that are temporal either take care of themselves or “grow strangely dim”.
Remember at the wedding feast at Cana? Mary wanted Jesus to fill the family's need when she told Him, "they have no wine". Jesus' response was pretty clear when He said, "What is that to Me and to you, woman?" (Literal Translation)
Jesus wasn't at this marriage feast to fulfill the family's needs, but that He "...manifested forth his glory".
I believe it's the same with our material needs. As long as we seek first the kingdom of God, all these other things will be added unto us. (Matthew 6:33)
In Christ...Alone!
