ALWAYS

"Let your garments always be white and let your head lack no oil."
    Ecclesiastes 9.8


It is difficult to live in a world that is so entangled in sin and yet maintain your garments white. However, it is not impossible. The secret behind maintaining yourself pure in an impure world is fearing the Lord and obeying His voice. The more sinful you are, the more effective God's power is. 
The Almighty never asks for something that is impossible to do.
