Is that what you think? Verse 50 says,
Matthew 12:50
"For whoever does the will of my Father in heaven is my brother and sister and mother.”
In Luke 11:27-28
As Jesus was saying these things, a woman in the crowd raised her voice and said, “Blessed is the womb that bore You, and blessed are the breasts that nursed You!” 28 But He replied, “Blessed rather are those who hear the word of God and obey it.”…
Jesus is saying, that it is far greater to hear the gospel message, and embrace who He is, and believe on Him, and in Him, and have a heart that that is conformed to Him and fully relies on Him by FAITH. Jesus was pointing out that this is is far greater than to be related to Him in the flesh.
Both zacchaeus and the tax collector in Jesus' parable believed who Jesus was, and relied on His mercy and grace. They understood that they were sinners, and in need of God's UNMERITED grace. You were too anxious to point me into the direction of Mary and make the conversion all about her instead of about Jesus.
