Romans 12:13

‘Communicating to the necessities of the saints; given to (pursuing) hospitality.'

And as pilgrims on life's journey (1 Peter 2:11) we are to aid our fellow pilgrims en route, as we ensure the meeting of their necessities (food and clothing) where needed, and provide them with hospitality (Matthew 25:35). Thus we aid in the fulfilment of Christ's promise to His disciples (Matthew 6:33). Note that hospitality has to be ‘pursued with vigour'. It was a privilege that was to be ‘sought eagerly', and indeed carried the assurance that it would result in blessing (Matthew 10:12). In Paul's day such hospitality was especially important, for on the whole inns were not pleasant places to be, whilst often those who were serving Christ, (and there were many travelling around in His service), were subjected to harassment either by the mobs or by the authorities, just as Jesus had warned (Matthew 10:14). Paul himself had benefited by such hospitality. Thus a welcoming environment was a great blessing to the travelling Christian, even though it could sometimes be costly for all concerned (compare Genesis 19:9; Judges 19:22).
