In Galatians 4:6-7 Paul tells us that we have access to the same intimacy with God the Father that God the Son, Jesus Christ had. Jesus addressed God the Father as “Daddy” when He prayed, Abba, Father, as recorded in Mark 14:36. Listen to Paul’s words carefully as he doesn’t say we “whisper” Abba, Father as if we are lacking confidence to speak affectionately. No, we are bold and confident to shout out our love for we have experienced His love for us. Our cries, as weak as they may seem in a world that belittles our faith, mocks our life and attempts to drown out our voices will never be able to keep our Dad from hearing us! God’s purpose was not only to secure our sonship by His Son, but to assure us of it by His Spirit.
To be an heir you must inherit something but we don’t inherit something we inherit Someone, God the Father! And as such we have received according to Eph. 1:3 we have also received “every spiritual blessing in the heavenly places in Christ”.
