Jesus uses Family language
Last time Jesus spoke about brothers or sisters was Matthew 12:48-50 'For whoever does the will of my Father in heaven is my brother and sister and mother.” Pointing to his disciples, he said, “Here are my mother and my brothers. He replied to him, “Who is my mother, and who are my brothers?”
After this chapter, Jesus has a massive thread of family language!
' “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. ' Matthew 18:15
Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother or sister who sins against me? Up to seven times?” Jesus answered, “I tell you, not seven times, but seventy-seven times. Matthew 18:21-22
'And everyone who has left houses or brothers or sisters or father or mother or wife or children or fields for my sake will receive a hundred times as much and will inherit eternal life. ' Matthew 19:29
In there, Jesus talks about a husband and wife and being a child in God’s kingdom.
Why all this family language?
Because he’s the Son, and so sure of his identity in the father!
