Romans 8:15-19

So you have not received a spirit that makes you fearful slaves. Instead, you received God’s Spirit when he adopted you as his own children. Now we call him, “Abba, Father.” For his Spirit joins with our spirit to affirm that we are God’s children. And since we are his children, we are his heirs. In fact, together with Christ we are heirs of God’s glory. But if we are to share his glory, we must also share his suffering. Yet what we suffer now is nothing compared to the glory he will reveal to us later. For all creation is waiting eagerly for that future day when God will reveal who his children really are.
