As the "certain Samaritan" journeyed he found the poor man who had been going down from Jerusalem to Jericho in a pitiable plight beside the road. Without the action of the Samaritan the man would have died, but this stranger—picture of the Lord from heaven—came right where he was and mercifully met him in his dire need.
The Epistle to the Romans describes the condition to which sin had reduced man, and also shows that only mercy would meet his case. This mercy on a righteous basis is beautifully unfolded in this epistle.
But the Samaritan did not leave the rescued man to shift for himself; that would never do. He put him on his own beast and took him to the inn where he could be taken care of. And, before leaving him there, he made every provision at the inn for his keep until the day he would return.
The next epistle—the First Epistle to the Corinthians—brings us to the inn, the Church of God. There we find that every provision has been made for our sustenance while down here awaiting the return of our Lord Jesus Christ. In the "inn" is the Spirit of God, and every member is to function in his own place. The assembly on earth is the place for the care of the saints—rescued sinners. This epistle also gives full directions for the right ordering of the "inn."
Then all of the other epistles come in their places as the proper food and instructions for those at the "inn." No need can arise for which provision has not been made. All of the troubles and abuses that would come into the Church were anticipated and full directions written out.
May we appreciate the grace that met us in our need. May we value the "inn." May we be found gathered together in the assembly to receive the food prepared for us by the One who has gone away and is coming back.
