There is nothing wrong with being casual, however, when one dresses sloppily it speaks volumes about lack of discipline, disrespect and lack of manners.
Christian should never dress in a sloppy way that causes a lack of proper respect for others and discipline in lifestyle.
On one occasion I arrived early to speak at a large church, and was finally met by the pastor who was extremely sloppy;
grubby dirty jeans, winkled shirt, uncombed hair, unshaven face,
needing a bath and wiping the sleep from his eyes. Jokingly I asked if
he had a fight with his wife and she had made him sleep in the car with
the dog all night? He answered with a smile admitting that he did look
As God's people let us dress in a way that will not bring disrepute to the name of Christ.
