The Lord says: “These people worship me with their mouths, and honor me with their lips, but their hearts are far from me. Their worship is based on nothing but human rules.
But now you know the true God. Really, it is God who knows you. So why do you turn back to those weak and useless rules you followed before? Do you want to be slaves to those things again?
So be careful and do not refuse to listen when God speaks. Others refused to listen to him when he warned them on earth, and they did not escape. So it will be worse for us if we refuse to listen to God who warns us from heaven.
