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.”
Fear can be a powerful influence in our lives. It’s really just the enemy’s perversion of faith. The word Abba was a term little children used in addressing their fathers. It would be similar to our word Daddy. It is less formal than Father and denotes a comfortable closeness between a child and his or her father.
Jesus said we could call God ‘Abba’ because He had delivered us from all fear. He will always take care of His beloved children, and we can approach Him without fear of rejection. When we run to Him with any problem or pain, He’s waiting with open arms to comfort and encourage us.
