We "easy believers" get the "whole message" unlike those who would pervert the gospel and attempt to put us back under bondage making Christ of no benefit.
Galatians 5:2 Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. 3 For I testify again to every man that is circumcised, that he is a debtor to do the whole law. 4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
Those who would "trouble us" trying to put us back under the law should read Galatians 5 paying close attention to verse 12.
Like I said, you read the words but cannot understand the clear meaning. Galatians 5:2 is a perfect example. Paul is comparing following Judaism to following the Way.
Somehow that fact seems to get lost on all easy believers.
