What does the Bible say about being my brother's keeper?

In Genesis 4:9, when Cain asks, 'Am I my brother's keeper?', it signifies a profound question about personal responsibility for others. As Christians, we are called to care for each other's spiritual and physical needs, embodying the love of Christ. While we cannot bear the weight of another's salvation—as each person is accountable to God for their own sins—we are still responsible to support and assist one another in the faith. The notion of being one's brother's keeper emphasizes the importance of community and mutual care among believers.
