5 For this reason, when I could no longer endure it, I sent to know your faith, lest by some means the tempter had tempted you, and our labor might be in vain.
6 But now that Timothy has come to us from you, and brought us good news of your faith and love, and that you always have good remembrance of us, greatly desiring to see us, as we also to see you —
7 therefore, brethren, in all our affliction and distress we were comforted concerning you by your faith.
8 For now we live, if you stand fast in the Lord.
know (v.5) = ascertain, come to know, gain knowledge of — progress in knowledge as opposed to full knowledge
lest by some means the tempter had tempted you (v.5) — 2 Corinthians 11:2-3
tempter (v.5) — Satan — Matthew 4:3
tempted (v.5) — Peirazo, means, first, to attempt to do something, to assay, as in Acts 9:26; 16:7; 24:6; then, to make trial of deliberately, as the Queen of Sheba made trial whether Solomon were as wise as he was reputed to be, 1 Kings 10:1; and as the Pharisees made trial of the integrity of the Lord Jesus, Matthew 19:3; 22:18, and many places; or unconsciously, but not less really, as those who sinned in the wilderness made trial of the holiness of God, 1 Corinthians 10:9, cp. Hebrews 3:8-9; as Ananias and his wife made trial whether the Holy Spirit were indeed with the church, Acts 5:9; and as the Jewish believers made trial of the grace of God, Acts 15:10. — Vine, page48.
our labor might be in vain (v.5) — “might be without results” — 1 Thessalonians 2:1 —Paul wasn’t saying that the Thessalonian believers could lose their salvation. They couldn’t. But they could lose their joy and comfort found in the grace message and also their testimony to those around them if they fell victim to Satan’s temptations.
good news (v.6) = gospel — used in the Septuagint of any message calculated to have a cheering effect on those who receive it — the word “gospel” in Scripture, doesn’t always refer to the plan of salvation during this current dispensation
your faith and love (v.6) — 1 Thessalonians 1:3 — The fact that Paul didn’t include hope here is significant in light of their confusion regarding the resurrection (see 1 Thessalonians 4:13 and following).
good (v.6) = inherently good, good in nature
remembrance (v.6) — always used in connection with prayer (Philippians 1:3; 2 Timothy 1:3)
therefore (v.7) — because of Timothy’s report (v.6)
affliction (v.7) = used by Paul to refer to persecution at the hands of men, including mobs and rulers
distress (v.7) — Paul sometimes uses this word of an inward pressure of spirit, as in 1 Corinthians 9:16, “necessity”; sometimes of lack of material things, 2 Corinthians 6:4; 12:10, and here. — Vine, page 49
