We have been chosen, grafted, adopted into the family of God. And now that we are a part of the family, the Spirit causes us to call out “Abba! Father!” Remember that Abba is the most intimate form for referring to a father. It is like saying “Daddy”; it connotes a deep level of familiarity and intimacy. As God’s Spirit speaks to our hearts, we can call out to God as our Abba. We will begin to experience this intimate relationship more deeply than we ever thought possible, so much so that we will begin to wonder, Does everyone feel this loved by God?
