“Then the word of the Lord came to Zechariah saying, ‘Thus has the Lord of hosts said, ‘Dispense true justice and practice kindness and compassion each to his brother; and do not oppress the widow or the orphan, the stranger or the poor; and do not devise evil in your hearts against one another.’” (Zechariah 7:8-10)
The Bible is centrally focused on one person: Jesus Christ.
The Bible is secondarily focused on one command: love your neighbor, and take care of them, as yourself, regardless of the color of their skin, regardless of the language they speak, regardless of the diseases they are victimized with, regardless of their gender and sexuality, and regardless of how far they are in geographical proximity to you.
These are the common themes that weave the grand narrative of the Bible together to form one cohesive message:
Come to faith in Christ, and live in faith for Christ.
