2 Corinthians 6:1

As workers together with Him [σ υ ν ε ρ γ ο υ ν τ ε ς]. Lit., working together. With Him is implied in the compounded oun with. That it refers to God, not to the fellow - Christians, is evident from the parallel 1 Corinthians 3:9, laborers together with God, and because the act of exhortation or entreaty in which the fellowship is exhibited is ascribed to God in ch. 5 20. The phrase Qeou paredroi assessors of God, occurs in Ignatius' letter to Polycarp. Compare Mark 16:20.

In vain [ε ι ς κ ε ν ο ν]. Lit., to what is vain. Equivalent to the phrase to no purpose.
