"For he will order his angels to protect you wherever you go" "For He will give His angels orders concerning you, to protect you in all your ways" (Psalm 91:11, NLT, HCSB).
Troubles abound in life. No one's life is ever trouble free. No one's life is ever always a bed of roses. We may not think so, but even Bill Gates' life is hard. Life gets better, then it gets worse. Uncertainty in life is a certainty. Unpredictability should be predicted. Unexpected events should be expected. Life is like that.
How do we deal with such a life? Psalm 91 deals with such a life head on. Simple trust will bring us into a place of strong defense (Ps 91:2), the personal warmth of divine care, pledged defense (Ps 91:4) and a host of heavenly guardians every step of the way (Ps 91:11). Psalm 91 wants us to know that those who truly trust God are a protected species.
