If someone is clean and good inside, then everything is clean and good for them to enjoy. But if someone is not a believer and has a dirty mind, then nothing is clean or good for that person. Their minds have become spoiled. They no longer feel guilty when they do anything wrong. Titus 1:15
在潔淨的人，凡物都潔淨；在污穢不信的人，甚麼都不潔淨，連心地和天良也都污穢了。 提多書 1:15
