when He comes to be glorified in His saints on that day [that is, glorified through the changed lives of those who have accepted Him as Savior and have been set apart for His purpose], and to be marveled at among all who have believed, because our testimony to you was believed and trusted [and confirmed in your lives].

Let no one in any way deceive or entrap you, for that day will not come unless the apostasy comes first [that is, the great rebellion, the abandonment of the faith by professed Christians], and the man of lawlessness is revealed, the son of destruction [the Antichrist, the one who is destined to be destroyed],

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.
