Who your parents are makes a big difference in your life. If you are in Christ, you are a child of the living God. The Holy Spirit teaches your spirit to cry Abba because God is your Father. Kids of royalty grow up knowing there is an inheritance and a kingdom to be handed on to them in time. What about children of God? Knowing what is coming, we can endure the travails of life in our times. Suffering looks different when you have a future secured in God (v. 18). We can have enduring hope—like a mother who hopes for the good of her child--enduring hope that the Day of the Lord is coming.
