Mat 5:9 Blessed [are] the peacemakers: for they shall be called the children of God.
Some children are called trouble makers, causing troubles all over the place.
They are not solutions to any problem, rather they perpetuate them. We are glad because our own children are peace makers, and they are called God’s children.
To be called the children of God means they have attributes that are like God in behavours and attitudes.
My children are peace makers among their friends in life. They are also called the children of God. God cares for my children because He is their daddy, He also blesses them.
