Our Father does not want you to remain in an attitude towards him as a servant, but as united in an understanding and loving relationship with him. Not in sacrifice is saying not because you have to, but in belief is saying because you want to. As we grow in knowledge and understanding of God(ALHY), his will and his ways; we grow in love for him and one another; just as a husband to his wife, a wife to her husband, and we all for one another... doing for each other out of love.
