A lot can change in a minute. We all know the cliches about a week being a long time (in politics), and a lot can happen in a day, but the truth is that life can change completely in less than a minute.
When Paul wrote to the Christians in Ephesus, he wasn’t writing to strangers. He knew these people. He had preached to them, wept with them, prayed with them, and watched God save them. Their story begins in the book of Acts, continues through Ephesians, is strengthened in 1 & 2 Timothy, and is warned again in Revelation.
And through it all, one message shines:
Salvation is God’s plan, God’s work, and God’s gift — not ours.
1. How the Gospel First Reached Ephesus (Acts 18–20)
Ephesus was a city full of idols, magic, immorality, and spiritual darkness. But God had a plan for them before the world began (Ephesians 1:4).
In Acts, we read:
• Paul preached the Gospel boldly.
• Many believed in the Lord Jesus.
• People burned their magic books.
• The whole city was shaken by the message of Christ.
This is what the Gospel does — it rescues, changes, and transforms.
“Believe on the Lord Jesus Christ, and you shall be saved.”
— Acts 16:31
Not “behave better.”
Not “try harder.”
Not “keep the rules.”
Just believe.
If you’ve ever wondered what Christianity is really about — rules or rescue, effort or grace — the book of Galatians answers it plainly. Paul writes like a man on fire because the very heart of the Gospel was under attack. Some were teaching that you needed Jesus plus good works, Jesus plus the law, Jesus plus human effort to be saved.
Paul says absolutely not.
The Gospel is Christ alone, grace alone, faith alone — or it is not the Gospel at all.
1. The Problem: People Adding to the Gospel
Some teachers had slipped into the churches of Galatia, saying:
“You need to keep the Jewish law to be saved.”
“You need to do certain works to stay saved.”
“You need to earn God’s acceptance.”
Paul responds with the force of a man defending the cross:
“If righteousness comes by the law, then Christ is dead in vain.” — Galatians 2:21
In other words, if you could save yourself by being good, Jesus didn’t need to die.
If 1 Corinthians was Paul taking the Corinthians by the shoulders and saying, “Brothers and sisters, this needs sorting,” then 2 Corinthians is him saying, “Thank you for listening — but some of you still need to take God seriously.” It is one of the most personal, emotional, and Christ‑centred letters Paul ever wrote.
1. A Letter of Thanks — and a Call to Finish the Job
Many believers in Corinth had responded well to Paul’s first letter. They had repented, corrected the immorality, and taken sin seriously. Paul rejoices in this. He says God “comforts the downcast” and that he was comforted when he heard of their obedience (2 Cor. 7:6–7).
But some still resisted. Some still questioned Paul’s authority. Some still refused to repent. So Paul writes again—thankful, relieved, yet still urging them to fully submit to the Lord.
This is the Gospel pattern:
