Well I for one have never seen an angel, I would love too, but I can wait till I get to heaven. Honestly I much rather see the face of Jesus while on earth. But my Dad and brother have seen angels, hope you don't mind that I sure a couple of their stories.
When my Dad's first wife died, it hit him in a really hard way. In fact he never really got over her death. Anyway, when she first died, my Dad would cry out to God and ask him, "WHY DID YOU TAKE HER?!!! My Dad told me of stories where he would go out in the country and just scream, from all the pain. One night he was lying in bed with his eyes closed, he was in anguished, thinking about his deceased wife. All of a sudden he felt like something had just sat down on his bed. When he opened his eyes he saw a big angel, surrounding in light. Well he said it scared him, I mean the thing had just came out of nowhere, lol. He said, then the angel smiled at him, and lightly place it's hand on his head. Once the angel touched him, my Dad fell into a deep and peaceful sleep. He knew then God's was with Him, and that he heard his cries.
Now on to my brother. My brother is 13 years younger than me. Our Dad passed away when my brother was 13, it was hard on us all, but hard on my brother the most, they were best friends. My brother had said if anything ever happened to our Dad he would commit suicide. My Dad was real ill for years, but fought to stay alive for my brother. Once my Dad died, God has started giving my brother visions. The first was God showing how my Dad died. Our Dad was lying in the hospital room, when two huge angels came to each side of the bed. My brother made a point of just how big these things were, I guess he didn't expect them to be so big. Mostly we see pictures of human sized angels or baby angels. Well Dad open his eyes, and the angels told him, "It's time to go.". My Dad said, "Not yet." The angels then repeated, "It's time to go." My Dad then said, "Okay." Once that happened, my Dad's spirit lifted out of his body. When his spirit was coming up, he started touching his mouth, my dad had false teeth, and I guess he was realizing he had his teeth back, lol. My brother said that my Dad looked young, no glasses, no grey hair, just young and that his hair which was full at this point had some type of sheen to it. Then my Dad turn around and looked at his body and kinda just shook his head. Then my dad's spirit went up accompanying by the Angels. I could say more about this vision, but I will stop there. Since then my brother has received many visions, his even seen the face of Jesus and visions of Heaven. He doesn't realized how bless he is to witness the things he has seen.
When my Dad passed away, my brother was very very angry. He said that Daddy had lied to him, because he promised when he got well, they would go ride bikes. In a way it was almost like he blame my Dad for dying. My Dad always said he didn't want to leave my brother without a father and he didn't want to hurt any of us by dying, since he knew the pain of losing his first wife. When my brother had that vision, he realized that it was not my Dad's choice to leave, just simply time to come home. Since then he is not upset anymore, because he knows he will see my Dad again in heaven. Sometimes he has to reassure my mom, that Daddy is okay, and we will see him again.
So while I agree that one most be careful when talking about angels, testing the spirits, and to make sure you do not worship them. I think it is good encouragement to hear stories from others how God will send his Holy Angels for children, how cool is that. We are truly not alone in this world, God is there for us, and sends His angels to do His will, just for us. Talk about feeling loved, huh?
