A bitter spirit leads to a frowning face!
Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled; Hebrews 12:15
Many in this life are walking around with wrinkles on their face because they have not dealt with strife in their life. They have swept issues under the rug so long that the issues are so large they are tripping over them and they have begun to stink up their life. Instead of following Biblical instructions they have ignored, dismissed, and even denied the issues exist becoming bitter old men and women.
Friend, if you have problems with your employer, talk with them. If you have issues with a fellow church member, talk with him/her. If you have ought with a sibling or parent, talk with them. Don’t put it off! If you do, you will eventually have a permanent frown on your face.
