"For those who are led by the Spirit of God are children of God. For you did not receive a spirit of slavery to fall back into fear, but you received a spirit of adoption, through which we cry, 'Abba, Father!'" - Romans 8:14-16
The Holy Spirit reveals many things to us. One of the most beautiful is the Spirit revealing God as our loving Father, our "Abba - Daddy." Jesus related to his Father as Abba and never before had God been spoken of in such personal and intimate terms. God as Abba is a uniquely beautiful Christian revelation. The Spirit of Jesus desires to free us from fear and a master-slave relationship to give us a Father-Daughter or Father-Son relationship.
