4 But when the right time came, God sent his Son, born of a woman, subject to the law. 5 God sent him to buy freedom for us who were slaves to the law, so that he could adopt us as his very own children.*4:5 Greek sons; also in 4:6.6 And because we*4:6a Greek you. are his children, God has sent the Spirit of his Son into our hearts, prompting us to call out, "Abba, Father."*4:6b Abba is an Aramaic term for "father."
