Grace to you and peace [inner calm and spiritual well-being] from God the Father and the Lord Jesus Christ.

not to be quickly unsettled or alarmed either by a [so-called prophetic revelation of a] spirit or a message or a letter [alleged to be] from us, to the effect that the day of the Lord has [already] come.

and by unlimited seduction to evil and with all the deception of wickedness for those who are perishing, because they did not welcome the love of the truth [of the gospel] so as to be saved [they were spiritually blind, and rejected the truth that would have saved them].

But we should and are [morally] obligated [as debtors] always to give thanks to God for you, believers beloved by the Lord, because God has chosen you from the beginning for salvation through the sanctifying work of the Spirit [that sets you apart for God’s purpose] and by your faith in the truth [of God’s word that leads you to spiritual maturity].

Now may the Lord of peace Himself grant you His peace at all times and in every way [that peace and spiritual well-being that comes to those who walk with Him, regardless of life’s circumstances]. The Lord be with you all.
