Why is it important for Christians to help others?

Christian hospitality and charity are essential components of walking in truth, as seen in the instruction to help both brethren and strangers. In 3 John 5, John commends Gaius for his faithful service to both familiar and unfamiliar believers, highlighting that such acts of love reflect the nature of Christ. This hospitality serves to strengthen the community of faith and demonstrates the practical application of the Gospel. By meeting the needs of others, Christians not only fulfill a divine command but also create opportunities for the truth of Christ to be shared and lived out among those who may not yet know Him.
