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.
