Protecting yourself from the temptations of this world begins one choice at a time.
Romans 12:21, Be not overcome of evil, but overcome evil with good.
When you finally get up this morning, you will begin to make choices for the day. The choice to get up or not. The choice of what you eat for breakfast. The choice on whether you will go to work or not. While those choice are somewhat trivial, when you chose to do your devotions, read your Bible, or share the Gospel, those things are very much important to your Spiritual success.
Will you prepare for the last day of this week better than you started it off? Will you be overcome with evil or will you overcome evil with good? It is determined by those first few choices of the day, so chose well!
