Today’s Bible reading is Galatians 1. Paul wrote the letter to the Galatians to counter a dangerous theology that added to Jesus’ once-for-all sacrifice.
A group of Judaizers (not just “Jews”) said that Jesus’ death was sufficient for our forgiveness, but in order to be a good Christian, you have to be a good Jew, obeying the Old Testament Law, including the rite of circumcision. Paul was quite vocal in his response.
I am amazed that you are so quickly turning away from him who called you by the grace of Christ and are turning to a different gospel—not that there is another gospel, but there are some who are troubling you and want to distort the gospel of Christ.

I’m glad that the Christian Standard Bible brings out the differences in Paul’s word choices that some other translations gloss over. By using the words different and another, the CSB points out that the gospel preached by these Judaizers is not just a little different from the gospel that Paul (and the other apostles) preached.

If you are a believer, a true child of God, you don’t have to add to your salvation (as if you really could!). Jesus accomplished everything necessary to make you righteous in God’s eyes. Because of what Jesus did, your salvation has been fully secured. You don’t have to — and you cannot — add to what He has done to make God any happier with you than He already is!
Sure, with being a child of God, there are commands in Scripture that still apply, but you can obey with a completely clear conscience and obey since you already have a relationship with your Father — as opposed to obey in order to have or maintain a relationship with Him.
That’s good news! That’s the gospel!
