Rt Rev Christopher Lowson was responding to comments by the county's chief constable who has said there will be stark choices unless further funding is available.
The budget is still being set but the chief constable has warned of possible cuts to road policing, crime investigations and community and neighbourhood policing.
Bishop Christopher Lowson said: "I am willing to be a voice to ensure where possible Lincolnshire and its police officers get a fair deal and we do not lose further police from our communities.
"From a young age, I was taught if I was in difficulty I could always approach a police officer - less money and less services means there may be no-one to approach."
Bishop Christopher said the situation was a wake-up call for the community and government.
The bishop visited local schools in Spalding in the south of the county this week and was welcomed and hosted at St Mary's Cowbit by the school's mini police. The initiative involves senior school pupils meeting local police and they are given a uniform with a role in the school to promote good behaviour.
Bishop Christopher added: "The mini police are just one example of community based policing that is so valuable.
"A thinner blue line in our county would be a loss to the community."
