You should live such good lives before [unconverted] Gentiles, so that even though they accuse you of being evildoers, by seeing your good deeds, they will [be led to] honor God [for you] on the day He visits us again [i.e., to bring judgment].
However, these people are like unreasonable, ignorant creatures of instinct, born as animals which are [to be] caught and destroyed. They speak out against things about which they are ignorant. In [the process of] destroying others, they will certainly be destroyed themselves.
Now they knew who God was, but they did not honor Him as God or thank Him [for their blessings]. Instead they engaged in their useless speculations and their foolish minds were filled with [spiritual] darkness.
But these people [i.e., the “certain men” of verse 4] speak against whatever they do not understand, and what they do understand naturally, the way animals do, proves to be their ruination.
[even] though I had previously spoken against Christ, and persecuted [Christians] and acted outrageously. However, I obtained mercy because I acted out of ignorance, not believing [in Christ].
For we [Christians] were also once foolish, disobedient, deceived, enslaved to various kinds of [evil] desires and [sinful] pleasures. [We used to] live in malice and envy, hating people and being hated by them.
You foolish people [of the churches] of Galatia [Note: This was a province in present-day Turkey], who tricked you? Was not Jesus Christ graphically portrayed before you as being put to death on a cross?
May your conscience be able to so approve of your conduct that, even if you are ridiculed, those doing it will [eventually] have to be ashamed [of themselves] for criticizing your Christian behavior.
