Psalm 100:3"Know ye that the Lord He is God. It is He that made us and not we ourselves. We are His people and the sheep of His pasture."
God made us for Himself, we are His people.
Some may reject His ownership but it is not His fault, He made us to be His own.
The same way the sheep belong to the shepherd. Some may run away, some are too dumb to stay with the shepherd, and so go their own way. They then become lost.
It is the ones who stay with God who are his own, to stay in His pasture.
They will be saved, at home with God.
Simple but true !
