4 But when the right time came, God sent his Son to make us free. He was born by a woman during the time when men had to obey the law.5 God sent him to set the people free who were under the law. God sent him so that we would receive our rights as sons of God.6 Because you are sons, God has sent the Spirit of his Son into your hearts. The Spirit calls out, Father!7 So then, because of what God has done, you are no longer a slave but you are a son. And because you are a son, you will receive what he promised.
