<p>4:28 <i>Brothers: We, as Isaac was, are children of promise</i>- Note the warmth of the language. These &quot;brothers&quot; had chosen Judaism, and Paul has just told them that Christ must be formed in them again seeing they are devoid of the Spirit, not experiencing the promised &quot;blessedness&quot;, and had effectively precluded themselves from salvation by seeking to achieve it by works. He felt his work for them had been in vain. And yet Paul now speaks of them as if they are saved, and his full brothers. Likewise he says that the Lord still ministers the Spirit to them and ministers amongst them (3:5). It could be argued that Paul's protestations about the Galatians were exaggerated and reflective of how he had become far too personally invested in them. Or it could be that as with the Corinthians, he accepts them as his brethren in Christ by status, assuming their salvation because it was not for him to condemn them; whilst at the same time openly facing their failures and addressing them.</p>
