ибо свидетельство Христово утвердилось в вас, —
Even as the testimony of Christ was confirmed in you:
even as the testimony concerning Christ was confirmed in you,
even as the testimony about Christ was confirmed among you —
God thus confirming our testimony about Christ among you.
even as the testimony of Christ was confirmed in you,
This confirms that what I told you about Christ is true.
(according as the testimony of the Christ has been confirmed in you,)
