My concern was because of the false brothers [those people masquerading as Christians] who had been secretly smuggled in [to the community of believers]. They had slipped in to spy on the freedom which we have in Christ Jesus, in order to bring us back into bondage [under the Law of Moses].

This [deceptive] persuasion is not from Him who called you [to freedom in Christ].

It is my own eager expectation and hope, that [looking toward the future] I will not disgrace myself nor be ashamed in anything, but that with courage and the utmost freedom of speech, even now as always, Christ will be magnified and exalted in my body, whether by life or by death.

Let no one defraud you of your prize [your freedom in Christ and your salvation] by insisting on mock humility and the worship of angels, going into detail about visions [he claims] he has seen [to justify his authority], puffed up [in conceit] by his unspiritual mind,

For certain people have crept in unnoticed [just as if they were sneaking in by a side door]. They are ungodly persons whose condemnation was predicted long ago, for they distort the grace of our God into decadence and immoral freedom [viewing it as an opportunity to do whatever they want], and deny and disown our only Master and Lord, Jesus Christ.
