This devotional is what prompted me to study all the verses in the Bible about "the angel of the LORD." It really is a facinating study.

"The angel of the LORD encamps all around those who fear Him, And delivers them." Psalm 34:7

A thorough study of the scriptures upon each mention of "the angel of the LORD" finds a very intriguing puzzle. Just who the identity of this angel is remains a mystery. I find it quite possible that this doesn’t refer to just one individual, but that there may have been more than one "angel of the LORD." There are at least two references when a person or group of people bowed down to this "angel" and the worship was accepted. (Numbers 22:31; 1 Chronicles 21:16) This seems to indicate that the "angel" may in fact have been some sort of physical manifestation of God. An angel would not have accepted obeisance. (Revelation 22:8-9)
Regardless of the identity of the angel in this Psalm, ultimately our protection comes from God. To the saints, the Lord is many things. "The LORD is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower." (Psalms 18:2) Ephesians chapter 6 says that our whole armor as Christians comes from God (vs. 11-18). Did you realize that Ephesians 6 leaves out armor on the back? Roman soldiers did not protect their back because running from a battle was considered cowardice.
It is awesome to think that the creator of the universe has our back. This protection is better than the Secret Service! We have better security than the President of the United States!
This is not to say that a Christian never has trouble. Unfortunately we live in a world which includes sickness, sorrow and pain. James teaches us: "My brethren, count it all joy when ye fall into divers temptations (NKJV - "trials"); Knowing this, that the trying of your faith worketh patience." (1:2-3) It is not if we have temptations, but when. No one escapes the trials of this world until we reach our eternal abode.
And yet, as children of God, we have a lifeline. Hebrews four and verse sixteen tells us that we can "come boldly unto the throne of grace, that we may obtain mercy, and to find grace to help in time of need." I John 5:14 also teaches us that we can have confidence in anything we ask of God, that He will hear us.
How comforting it is to know that he is watching out for us. He is only a prayer away! There will also come a time when we will shed no more tears, feel no more pain, or say goodbye to another loved one. (Revelation 21:4) What a glorious day that will be when the Lord will no more have to defend the saints!
