The Lord will keep you from all evil; he will keep your life. The Lord will keep your going out and your coming in from this time forth and forevermore. (Psalm 121:7-8 ESV)
I got home from work yesterday shortly before my youngest daughter Elsa woke from her nap. After she got up, she wanted me to hold her for a while. As I carried her around the house, our eldest daughter Ali began tickling her. Elsa liked it of course, but then said "save me daddy!" We started this game of protection as I sought to keep my long armed Ali away from the tummy and neck of Elsa. I then told Elsa that she was right to ask me to protect her, for that is what I am called as her daddy to do.
I would love so much to be able to keep my children from all evil, yet I know this is an impossibility. If they were in the living room with me 24/7, I might have a decent shot at it, but the fact is I can not be in their presence every moment of every day.
God is a perfect Father; or maybe Dad is a more fitting word. He desires to keep his children from all evil just like I do, except in a complete and holy sort of way. He is uniquely equipped to do this job because he has all power, all knowledge, and can be everywhere all at once. He never needs to leave his children unattended in the living room as he heads off to work. He can do both, well actually all at once.
I could never promise my children that I will keep them from all evil. But we have contained here in the Bible just such a promise. God has all the resources to make good on this promise and only requires your faith to rest totally and completely upon his beloved Son Jesus. If you are a Christian, then you are in the verses' category of "you".
The Lord will keep you from all evil; he will keep your life. The Lord will keep your going out and your coming in from this time forth and forevermore.
