I have read the Gospels and I know that the devil loves the vague, gray areas. We are to admonish the sinner, not condone the sin. There is such a thing as objective truth and Jesus is Truth. He did not come to abolish the laws, but to complete them. Matt 5:17
"In the presence of God and of Jesus Christ, who will judge the living and the dead, and in view of his kingdom, I give you this charge. Preach the word; be prepared in season and out of season; correct, rebuke, and encourage - with great patience and careful instruction. For the time will come when people will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what itching ears want to hear. They will turn their ears away from the truth and will turn aside to myths. But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry. 
2 Timothy 4:1-5

 The Truth will set you free.
