No, we're not "all God's children." That's a leftist revision of a biblical God.
Some are children of Satan. Jesus said so.
Paul said to the Athenians Acts 17:"29 Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising."
There is a balance point between the two, for Jesus did call them Children of Satan, and John did, too in 1 John 3: "In this the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God, nor is he who does not love his brother."
John 8:44 "You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it."
My way of balancing it is to say that all of us originate from God, but some of us have chosen Satan's army.
“Some are children of Satan. Jesus said so.”
The irony is that Jesus here is referring to the Hypocritical Holy men of his generation who strained a gnat while swallowing a camel. A evil sinner named Chablis helplessly pushed to the ground by a angry mob in a righteous fever. Eager to mete out gods vengeance!
These Hypocrites tried to lay a trap for him with their ‘laws’. Jesus stepped in the middle of it and called them out saying “Who’s here that hasn’t sinned in their lives can cast the first stone!”
We are called to spread the Good News. Healing and light. Not Darkness and judgement. Don’t look to me to cast the first stone. But you go ahead.
That’s the way I see it anyway.
peace out!
