Be not forgetful to entertain strangers, for by so doing some people have entertained angels without knowing it.
The text that is the inspiration for this word is from the beautiful story of Ruth from the bible. Ruth and Naomi had been widowed and left alone with no husbands nor means of life support. Ruth made a decision to follow her mother in law back into the homeland and trust here life to God. She was adopted as an Israelite and God blessed her life in eternal ways. It would be wonderful if read the whole story for yourself.
16 And Ruth said, Intreat me not to leave thee, or to return from following after thee: for whither thou goest, I will go; and where thou lodgest, I will lodge: thy people shall be my people, and thy God my God: 17 Where thou diest, will I die, and there will I be buried: the Lord do so to me, and more also, if ought but death part thee and me.
Ruth was a stranger who journeyed with her mother-in-law Naomi back into her homeland after they had lost their family. She came to Boaz a stranger. He was the kinsman redeemer to Naomi who showed great mercy and took on the responsibility of the widow and the stranger. Ruth became a member by marriage into the royal bloodline of Israel. The son she bore to Boaz was King David's grandfather.
These are principles we see as we are kingdom harvesters for Jesus. We love and invite strangers who are outside the covenant to set their heart in the Lord and to learn covenant. Those who come from a foreign country and don't know our language and customs are called strangers to the covenant of Christ. But Jesus died to redeem all men. He is their kinsman redeemer. His heart is set to show mercy and adopt them into his family of laborers in his harvest fields and to keep them where eh is for all eternity. .
Just as we were once without Christ, so are they. By the giftings of the Holy Spirit, we become as they are, so that we might win them.
That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenant s of promise, having no hope, and without God in the world:
Say not ye, There are yet four months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest.
