There are people out there who are UNSTABLE SOULS in the habit of getting their own way (vs 14). They have forsaken the right way (vs 15), they are seduced through lust of their flesh (vs 18), they are promised liberty (vs 19) but are actually servants of corruption and are brought into bondage.
THERE IS A WAY OF ESCAPE! THROUGH JESUS CHRIST!
If you don’t get out, the end is worse than the beginning (vs 20). It would have been better to have NEVER known the way of righteousness than to have known and TURN from the HOLY commandment. (vs 21)
Will you be like the DOG? Or the HOG? Returning to their own vomit or wallowing in the mire. (vs 22)
