When people are not right in themselves or if they have not been taught right, they feel completely comfortable in disrepecting the people of God. They dont have any conscience about it at all.
There are some people who have truly pure hearts. They make sure that they treat everyone with respect and if they do make a mistake, they make it right. But then there are some people who make disrespecting people a habit. It does not matter who they are speaking to or who they are in Christ, they have become hardhearted. They have all the reasons in the world on why they do this but many times they are based on a bad attitude.
It matters in life how you treat people and it really matters to God. When we use our own issues as an excuse on how we get to treat others, we heap curses upon our own heads.
I have always lived a life trying as much as I can to have a pure heart towards God and others. It does not matter who someone is-of high degree or low degree.
Hebrews 13:2
Be not forgetful to entertain strangers: for thereby some have entertained angels unawares.
1 Chronicles 16:22
Do not touch my anointed ones; do my prophets no harm
