For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship. And by him we cry, “Abba, Father.” The Spirit himself testifies with our spirit that we are God’s children. —Romans 8:15-16.
Ab-ba. Listen to a baby and you will hear these basic early sounds. Incredibly, Jesus showed us, and the Spirit enables us, to speak to God with these basic-to-a-baby syllables of familiarity, trust, vulnerability, dependency, and intimacy. The Spirit is our guarantee that we don’t have to be afraid of God. We must revere him and hold him in awe, but we can also approach him as our loving and tender Father who always listens to our hearts and seeks to bless our lives.
