The biblical answer to Cain's question 'Am I my brother's keeper?' is a resounding yes. In Galatians 6:1-5, Paul teaches that carrying one another's burdens is a fundamental Christian responsibility. This includes gently restoring those caught in sin and helping others through various struggles like illness, grief, and financial crises. While Jesus is our primary resource for our burdens, God often uses people to help people. Pride and comparison are the main obstacles that prevent us from carrying others' burdens. As Christians, we must balance carrying our own responsibilities while helping others with their heavy loads.
