We study the asymptotic behavior as p of the Gelfand problem

{ Δ p u = λ e u in Ω R n u = 0 on Ω .

Under an appropriate rescaling on u and λ, we prove uniform convergence of solutions of the Gelfand problem to solutions of

{ min { | u | Λ e u , Δ u } = 0 in Ω , u = 0 on Ω .

We discuss existence, non-existence, and multiplicity of solutions of the limit problem in terms of Λ.
