Literally the Greek is, ‘Stranger-loving to one another without grumbling.’ Christians are to be lovers of strangers (Hebrews 13:2) or, as the word intends, those who show hospitality, just as Israel was told to love and care for strangers, mindful of their own experience in Egypt as an alien people (Exodus 22:21; 23:9; Leviticus 19:34; Deuteronomy 10:19).
Are we inviting others to our home not because we care about them, but out of a sense of duty, perhaps because the church expects us to do so? Hospitality is a recognition that all that we have belongs to the Lord and is at his disposal. He desires us to use our earthly goods to help fellow believers because Christ is in them, and so we do good unto the least of these his brethren as we would do to him. We must not resent the expense and trouble to ourselves in showing hospitality because whatever we give freely and cheerfully to believers for Christ’s sake is given to the Lord and will be given back to us in heaven in far greater measure, for whoever gives a cup of cold water to drink in Christ’s name will by no means lose his reward (Mark 9:41). Faith teaches us to give freely without any sense of loss, for what we spend in terms of this world’s good will be transformed into everlasting goods in heaven by a marvellous process which turns what is perishable into what is imperishable. To lose is therefore to gain, and to give is to receive back from the Lord. If we want the blessing of the Holy Spirit in our church, we have got to be hospitable to strangers, open to speaking, welcoming one another, giving hospitality to each other, which is easy. It is only in the environment of love between believers that the Holy Spirit can really work.
