1 Peter 5:8-10 Be of sober spirit, be on the alert. Your adversary, the devil, prowls about like a roaring lion, seeking someone to devour. But resist him, firm in your faith, knowing that the same experiences of suffering are being accomplished by your brethren who are in the world. And after you have suffered for a little while, the G-d of all grace, who called you to His eternal glory in Christ, will Himself perfect, confirm, strengthen and establish you.
Philippians 4:8 Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, let your mind dwell on these things.
Be alert. Be aware of the things around you, what you are doing, what you are exposing yourself to. In order to ensure that we are healthy, happy, and prosperous, we must learn how to make good decisions and this process first begins with being aware of what surrounds us and how it affects us.
