What was the Galatians' initial experience of salvation?

Les explains that the Galatians' initial salvation experience was the same as that of Paul's other converts in pagan communities. When Paul came into a strange, pagan city with no fanfare, he confronted people with the Gospel of the grace of God, how Christ had died for their sin. They believed it and turned from their idols to the true and living God. The Galatians entered into such a joy of their salvation, realizing it was all of grace. But then, as happens today, they began to be bombarded with pressure to come back to their former ways, just as a new believer who comes under the power of the Gospel and enters into salvation by grace often faces constant pressure to return.
