Satan Hinders Gospel Advance
Paul wanted to return but “Satan hindered us” (2:18). The sermon shows Satan actively opposes the spread of the gospel and fellowship.
The Tempter’s Schemes
Paul feared the Tempter would tempt them and labor be in vain (3:5). The sermon lists common devices: hiding sin’s hook, painting sin as virtue, promoting pride, causing division, etc.
Affliction and Perseverance
They were destined for afflictions (3:3–4). The sermon calls for steadfastness under trial, not being moved or tempted to despair.
Balanced View of Satan
Not in everything (hyper-spiritualism) nor absent (rationalism). The sermon urges sober watchfulness: resist the devil and he will flee (James 4:7).
