What doctrines will Les never compromise on?
The fundamentals that cannot be compromised are who Christ is, His virgin birth, His identity as God the Creator, and His atoning work of the cross fully satisfying every requirement for salvation. Christ's resurrection and second coming are also non-negotiable.
Les explains that he is human and not above error, and he does not expect everyone to agree with him on everything. But on these fundamentals he will never compromise. He lists who Christ is or was, His virgin birth, that He is God the Creator, and that His atoning work of the cross completed every bit of God's requirement for salvation. He also holds that Christ rose from the dead and is coming again. He says he would rather go back and stay on the ranch than compromise these things, because he fears presenting error and misleading someone to miss heaven's glory.
