"Regarding evil, be like a child."
1 Corinthians 14 : 20.
Paul uses a verb with 'child' so that it means to act as a child, to be innocent as a child.
We see the spiritual greatness of children. No saved adult shows as much love, joy, peace, and forgiveness as a child.
The disciples argued who was the greatest spiritually.
Jesus showed them a child and said, "Unless you turn and become as a child, you will not enter the kingdom of Heaven."
Matthew 18.
Children are spiritually superior to saved adults. We may learn from them.
