1 John 3:1 Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
It is a promise and a privilege to be called the children of God. We Re brought into the family of God when are given a new life through faith in Christ. We are adopted as princes and princesses of the king of the eternal kingdom of God. This status gives us rights and privileges, particularly as heirs of the Kingdom.
When God called us His children He made Himself responsible for our life, health and wellbeing. He sets us free to be children while He blesses us with every good thing. For all which it is my duty to ”thank and to praise, to serve and obey Him.” As children of a good and responsible Father we don’t have a worry in the world. Oh, to be aware of our calling and status as children of the king!
Children in a healthy family normally have no responsibilities other than to obey their parents. They are free to play and to go to school. This is what God wants for His children: trust the Lord and enjoy life.
This promise makes us strangers to the world, for the world does know the Father, that is, it does enjoy the relationship that we do.
