The Customer Is Mostly Right
The most important lesson I ever teach younger engineers is this:
Solve the customer's problem, not the one you wish they had.
I call it The Parable of the Bridge Builder.
A wealthy man walks into a bridge builder's office.
"I'd like a suspension bridge," he says. "Six lanes. Railway line on top. Finest steel and concrete money can buy. Money is no object."
The bridge builder is intrigued.
"Where would you like this bridge?"
"In front of my house."
The builder blinks.
"...Why?"
"Well," the man replies, "there's a small dip in my driveway. When it rains, water collects there. Sometimes I step into the puddle and my shoes get wet."
He sighs.
"This cannot continue."
At this point, every engineer in the room has already designed twelve better solutions.
Fill the dip.
Level the driveway.
Build a small footbridge.
Buy the man rain boots.
Teach him to look down occasionally.
Problem solved.
Except...
The customer did not ask for any of those.
Professionals often fall in love with their solution instead of the customer's outcome.
Explain. Advise. Then Stop.
Your job is not to win an argument.
Your job is to explain the options.
Explain the costs.
Explain the risks.
Explain the trade-offs.
Then stop.
If the customer understands the consequences, the request is legal, ethical, and technically possible, the decision belongs to them, not you.
Too many consultants, architects, and software engineers spend enormous amounts of energy trying to save clients from decisions the clients are perfectly happy to make.
Sometimes the customer knows the cheaper option.
Sometimes they simply do not want it.
And that is okay.
The problem belongs to them.
The money belongs to them.
The consequences belong to them.
Your ego belongs to you.
The problem belongs to them.
The money belongs to them.
The consequences belong to them.
Your ego belongs to you.
Take the money.
Build the man's bridge.
But There Is a Deeper Lesson Here
The bridge-builder story is useful for engineers.
But it is also about something deeper than customer service.
It is about lordship.
There is a kind of obedience that looks almost obedient.
It nods respectfully. It quotes Scripture. It agrees that God is wise, sovereign, and very much in charge.
Then it quietly opens a spreadsheet and begins improving the requirements.
That is where many of us get into trouble.
One of the hardest lessons in the Christian life is learning that God does not call us merely to admire His wisdom.
He calls us to obey it.
God does not hire consultants.
He raises servants.
Consultants Advise. Servants Obey.
There is a profound difference between a consultant and a servant.
A consultant says:
"Here is what I think you should do."
A servant says:
"What would You have me do?"
That distinction runs throughout Scripture.
Abraham was not asked to optimize God's covenant. Moses was not asked to redesign the Exodus. Noah was not invited to improve the Ark's specifications. Joshua was not asked to critique the battle plan for Jericho. The disciples were not told to suggest a better way to feed the five thousand.
They were simply asked to obey.
From a human perspective, God's instructions sometimes look... inefficient.
March around a city for seven days?
Use trumpets instead of siege weapons?
Tell fishermen to cast the net on the other side?
Tell Naaman to dip seven times in the Jordan?
Use five loaves and two fish to feed a multitude?
If you were the project manager, you would probably schedule a meeting.
If you were the engineer, you would probably open Jira.
If you were Saul, unfortunately, you might improve the requirements.
Saul and the Danger of Edited Obedience
That is exactly where Saul got into trouble.
God's instruction was painfully clear:
Destroy everything.
Saul looked at the requirements and thought:
Technically... I have a better idea.
He spared the best sheep.
He spared King Agag.
His reasoning even sounded spiritual.
"We will sacrifice them to God."
How noble.
How completely wrong.
Samuel's response still echoes through history:
"To obey is better than sacrifice."
Saul did not reject God's assignment.
He edited it.
He became the bridge builder who decided the Customer did not really need a suspension bridge.
He built something he considered wiser.
That is often the birthplace of disobedience.
Not rebellion.
Optimization.
Sometimes our greatest temptation is not to ignore God.
It is to improve on His instructions.
Jesus Never Behaved Like Heaven's Consultant
Jesus lived the exact opposite life.
Again and again He said:
"I have come not to do My own will, but the will of Him who sent Me."
Jesus never behaved like Heaven's consultant.
He behaved like Heaven's perfect servant.
Even in Gethsemane, where every human instinct wanted another solution, He prayed:
"Not My will, but Yours be done."
That may be the greatest expression of obedience ever recorded.
The Father asked for a bridge.
The Son did not redesign it.
He carried the cross.
The Temptation to Improve God
There is a lesson here for all of us.
Sometimes we spend more time evaluating God's instructions than obeying them.
"Lord, would this not be faster?"
"Would my idea not work better?"
"Are You sure this is the best approach?"
Meanwhile, God is not asking for our consultancy report.
He is asking for our obedience.
Of course, this does not mean God discourages wisdom or creativity. Scripture celebrates both. But wisdom begins by recognizing whose project this is.
If God owns the kingdom...
If God carries the responsibility...
If God sees the end from the beginning...
Then perhaps the wisest thing we can do is trust that His specifications already account for variables we cannot even see.
Build the Bridge
Our role is remarkably simple.
Explain honestly.
Advise wisely.
Then obey faithfully.
In business, that may mean building the man's bridge after he has understood the trade-offs.
In discipleship, it means something even higher.
Take the blessing.
Build the bridge.
Exactly the way the Customer asked for it.
Faith is not improving God's instructions.
Faith is trusting that the Architect already knows why the bridge must look exactly the way He designed it.
That theme runs from Genesis to Revelation.
