When a car has very little fuel in the tank, we say it is running on fumes. 

It is moving forward, but warning signs indicate the vehicle is in trouble.  It won’t go very far unless something changes.  And the something is simple, it needs fuel.

The same thing happens with Christians too. They give the impression of keeping on spiritually, engaging with the church, and so on.  But there are warning signs, and they won’t go very far unless something changes. 

Again, the something that needs to change is relatively simple, they need fuel. Simply being around Christians and using Christian language is not enough. Without a vital personal relationship with Christ, they are merely running on the fumes of Christianity.

Warning signs

In a car, you have warning lights on the dashboard to alert you to an issue before it becomes a problem.  If you proceed far enough, the engine will start to sputter and make unusual noises. 

What are the warning signs when a Christian is running on the fumes of Christianity?

• Loss of joy: There are many reasons for a loss of joy, so do not assume that the spiritual tank is always empty when joy fades.  However, any warning light is a reason to investigate.  Indeed, when someone’s tank lacks the fuel needed, delight in the things of God and church life will only come in fits and starts.  The classic biblical example is Martha in Luke 10:38-42 – she was doing the right thing, but the joy was gone.


• Alternate fuels: Is work or a hobby suddenly becoming more significant?  Are they starting to find motivation and purpose in something other than Christ in a way that was not true earlier in their Christian journey?  Alternative fuels are attractive because someone struggling will see the alternative as more readily accessible and the goals more attainable.


• Blaming the church: It is very rare to hear someone drifting from church life and being honest, “Oh, I am staying away because I am not fuelling my soul, and so I feel awkward being around other Christians right now.”  It is much easier to talk about how the church does not meet their needs, and they don’t fit, the programs are not helpful, the other people don’t like them, etc.  Not every person being critical of the church is in a bad place personally, but many are.


• Verbal paper cuts: Sometimes it is not the full force explosions that hurt, but the subtle paper cuts.  Someone in a low place spiritually will often make little paper cuts with their words.  Little bits of gossip.  Little criticisms.  Little digs.  Maybe nothing significant enough to confront or challenge, but enough to leave you feeling that sting of an open wound when they walk away.


• Emotional outbursts: Sometimes, things do come out in full force explosions.  And, like a cornered animal, someone feeling spiritually empty can lash out and attack rather than admit their need and open themselves up to help from others.

Emergency measures

What do you do when someone is running on empty and about to run out of fuel and grind to a halt? 

• Re-fuel: To be blunt, they need to be in the Word of God and allow Him to minister to them.  But they may struggle to feed themselves if they have let their tank get too low.  Perhaps a friend can help them get into the Word and start back into a healthy pattern. 


• Recognize the emergency – How often do we pridefully persist on our path, ignoring all the warning signs?  Many a stranded motorist thought they could go a little farther before stopping for fuel.  Part of solving the problem will be humbly admitting the problem.  As long as pride continues to stir excuses and explanations, the fuel cap remains in place.  They must humbly acknowledge how they have allowed themselves to drift, how they have arrogantly felt they did not need to be in the Word personally, or how another sin has built a blockage between them and God.  Whether that is a giant skeleton in the closet or the “respectable” sin of personal pride, confession will be like a doorway to help for the struggling believer.


• Reach out for help: These are in the reverse order.  We need to be fuelled again, but often that won’t happen until the nature of the problem is recognized, and often that is hard to achieve without first calling out for help from another.  If you see the warning signs in a friend, encourage them to face the reality of their situation.  If you are desperate, you could point them to this post and ask if it resonates with them because you are concerned.  If you see warning signs in yourself, then get a friend immediately.  We tend to think that a renewed effort in my quiet times, or perhaps some alternative, will fix the issue.  A thimble of fuel won’t get you too far.  Call a friend and walk through it with someone.
