One of the practices that the Bible says we should carry out is burden bearing. Here are some passages to consider:
Galatians 6:2: Bear one another’s burdens, and so fulfill the law of Christ.
Romans 12:15: Rejoice with those who rejoice, weep with those who weep.
2 Corinthians 1:3-4: Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God.
