Being adopted into God's family involves suffering in this world and glory in the resurrection.
Like a child who has been stung by a bee, you can tell who our Father is by watching whom we instinctively run to, crying, "Father!"
The "Abba! Father!" cry is not about trying to sense God's Spirit inside us. It is a reassurance that our faith is real when we find ourselves turning to Christ in hard times instead of fleeing from Him.
