Angels are wonderful beings, beings of light created by God. The word angel comes from the Greek word "angelos" which means "messenger", so they are God's messengers. In the bible angels are mentioned many times.
For example in Psalms (91:11-12) it says:
"For he will command his angels
to guard you wherever you go.
They will lift you up with their hands
so that you will not stumble over any stone."
Another example in Daniel (6:20-21) says:
"Daniel! You are a servant of the living God and always at his service; could your God save you from the lions?
Daniel replied, "Long live the king forever! My God sent his angel to shut the lions' mouths, and they have done nothing to me, for he knows that I am innocent, nor have I done you, your majesty, any harm."
Their mission is to care for us, guide us, protect us and help us in our daily lives. So I invite you to begin a relationship with the angels.
