Galatians 4:8-12 - Do Not Be Enslaved Again
8 But at one time, you Gentiles, having no knowledge of God, were slaves to gods which in reality do not exist. 9 Now, however, having come to know God--or rather to be known by Him--how is it you are again turning back to weak and worthless rudimentary notions to which you are once more willing to be enslaved? 10 You scrupulously observe days and months, special seasons, and years. 11 I am alarmed about you, and am afraid that I have perhaps bestowed labour upon you to no purpose.
12 Brethren, become as I am, I beseech you; for I have also become like you. In no respect did you behave badly to me.
