This movie brought me happiness, that I rejoiced seeing the hands of God working. God's people are called "Saints" not angels. Apostle Paul says that the Saints will be "Like" angels.
God created Angels for His specific will. There will be a day, when Jesus return, His Saints will march with Him. That is in the book of Revelation.
Most people believe that when their loves ones dies, goes to heaven, they become Angels. That contradicts what the word of God says. Angelic beings are different from humans. Humans don't become angels when they die. They become Saints, if they really belong to God in the first place because they received Christ as Lord and Savior.
So, when the children saw their loved ones leading them away, they are really Saints, are "Like" angels.
Saints exist here on earth, those who are true followers of Jesus Christ, as it is in Heaven. God's Will have been done that day when He sent a Miracle that no one can explain, but it can be, to a body of a believer, who knows what the word of God says. If God says it, do you all believe it? I do.
Shouldn't we all have faith like little children? Jesus said yes.
The Little Children and Jesus
15 People were also bringing babies to Jesus for him to place his hands on them. When the disciples saw this, they rebuked them. 16 But Jesus called the children to him and said, “Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these. 17 Truly I tell you, anyone who will not receive the kingdom of God like a little child will never enter it.”
Luke 18:15-17
