BIG IDEA: Anything other than Christ alone as the grounds for acceptance by God = another gospel.

*6 safeguards against getting sidetracked by another gospel:

Rejoice in the Lord. (v.1)
Recognize (v.2)
Remember the truth. (v.3)
Review the evidence. (v.4-7)
Reaffirm what’s worth more. (v.8,9)
Refocus on relationship. (v.10,11)
