Thematic Bible: Who are members of the lord’s family

For all of those who are led by the Spirit of God are the children of God. 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." The Holy Spirit Himself bears testimony [along] with our [human] spirit that we are the children of God. read more.
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].

Do not team up with unbelievers [i.e., in close relationships, such as marriage, etc.]. For what do righteousness and wickedness have in common? Or, what fellowship can light have with darkness? And what harmony can Christ have with Belial? [Note: "Belial" means "worthlessness" and was used for referring to the devil]. Or, what does a believer have in common with an unbeliever? And what agreement is there between a temple of God and idols? For we are a temple of the living God, just as God said [Lev. 26:12], "I will live in them and walk among them [i.e., among His people]; and I will be their God and they will be my people." read more.
Therefore, the Lord says [Isa. 52:11], "You people should leave their company [i.e., unbelievers, verse 14] and separate yourselves from them, and do not touch anything unclean [i.e., their evil practices], and I will welcome you." The Lord Almighty [also] said [Hos. 1:10], "I will be a Father to you, and you will be sons and daughters to me."

While Jesus was still speaking to the large crowds, His mother and [half-] brothers were standing outside [of the large house. See 13:1] wanting to speak to Him. Someone [from the crowd] said to Him, "Look, your mother and your brothers are standing outside, wanting to speak to you." He answered the person who told Him, "[Just] who is my mother? And who are my brothers?" read more.
Then He stretched out His hand toward His disciples and said, "Look, [here is] my mother and my brothers!" "For whoever will do what my Father in heaven desires, is my brother and sister and mother."

Then Jesus' mother and [half-] brothers came and stood outside [i.e., of a large house. See Matt. 12:46-13:1]. They sent a message to Him, asking Him to come out to them. Someone in the large crowd that was sitting around Him said to Him, "Look, your mother and your brothers are outside looking for you." He answered them, "Who is my mother and who are my brothers?" read more.
Then He looked out over those gathered around Him and said, "Look, [here is] my mother and my brothers For whoever will do what God wants, that person is my brother, and sister and mother."

Then Jesus' mother and [half-] brothers came to Him, but they could not get near Him because of the [large] crowd. And it was told to Him [by someone], "Your mother and your brothers are standing outside wanting to see you." But He replied to them, "My mother and my brothers are those people who hear God's word and obey it."

But we do see Jesus, who was made a little bit lower than the angels [i.e., by suffering death as a human being], and was crowned with splendor and honor because He suffered death. It was by God's unearned favor that He would experience death for every person. For it was fitting that God, for whom and through whom everything exists, in order to lead many [of His] children to glory [i.e., heaven], would make the author [or, pioneer] of their salvation [i.e., Jesus] completely [qualified] through [His] sufferings. For, both the One who makes people holy [i.e., Jesus], and those who are made holy [i.e., Christians], all come from one [Father], and for this reason Christ is not ashamed to call them His brothers,
