There are teachings of men and religions which are doctrines of death; not life. Teachings which bind in sin, and offers no freedom from sin, is a doctrine of death.
Of course when we live in a society and culture of sin; who knows what is sin? Who knows what is right and/or wrong. According to our culture today the only thing wrong is to say sin is wrong if that is what they are living in. In other words to call adultery a sin is a sin, because you have offended the sinner.
Jesus came to give life to those who were living death sentences. We all are until we come to Christ Jesus Himself. Jesus saw the teachings of the Pharisees, and of Herod as leaven. In Scripture “leaven” or yeast is a type of sin which permeates, and goes throughout the “bread” causing it to rise, or puff up. Hear the words of Jesus:
“Now the disciples had forgotten to take bread, neither had they in the ship with them more than one loaf. And He charged them, saying, Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod.” Mark 8:14-15 (KJV)
Jesus addresses much of the leaven of the Pharisees in Matthew 23. They were making people more disciples of hell than they themselves were with their teaching. Herod was a political leader; and of that we need to be aware as well.
Religion and politics do mix well when they are corrupt. The religion of the day; in the day of Jesus and ours, and politics is deceptive, and corrupt.
There is life when one comes to Jesus believing Him, and turning from sin to life in Him.
