AUV(i)
15 For you did not receive the Holy Spirit, to enslave you again to fear, [Note: Some translators take “Holy Spirit” here to be “spirit,” making the verse say “you did not receive the spirit of slavery”], but you received the Holy Spirit [who produces] sonship, so we can call out, “Abba”, [which means] “Father.”
16 The Holy Spirit Himself bears testimony [along] with our [human] spirit that we are the children of God.
17 And if we are [His] children, then we have an inheritance from God [i.e., blessings here and hereafter] and are fellow-sharers with Christ [of such blessings], providing we [are willing to] suffer with Him, so we can also be honored with Him [i.e., in the future life. See verses 18-25].
18 For I consider that our present sufferings do not deserve to be compared with the glory that will be revealed to us [i.e., in the future life].
