1 Peter 1:20

Foreordained [π ρ ο ε γ ν ω σ μ ε ν ο υ]. Lit., and better, foreknown, as Rev. Manifested [φ α ν ε ρ ω θ ε ν τ ο ς]. Observe the difference in tense.

Foreknown is the perfect participle, has been known from all eternity down to the present : "in reference to the place held and continuing to be held by Christ in the divine mind" (Salmond). Manifested is the aorist participle, pointing to a definite act at a given time.

In these last times [ε π ε σ χ α τ ο υ τ ω ν χ ρ ο ν ω ν]. Lit., as Rev., at the end of the times.
