Matthew 5:13 You are the salt of the earth: but if the salt has lost his savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.
When salt is sprinkled or added to food, it changes the taste dramatically, so that everything in your pot is affected. Similarly, God has sprinkled His remnant people strategically throughout the earth, so that in certain instances, the inhabitants thereof might be beneficiaries of His assurance.
[The Great Controversy pp 631] The Lord delights in mercy; and for the sake of a few who really serve him, he restrains calamities, and prolongs the tranquility of multitudes. Little do sinners against God realize that they are indebted for their own lives to the faithful few whom they delight to ridicule and oppress.
Acts 16: 23 And when they had laid many stripes upon them, they cast them into prison, charging the jailor to keep them safely. 24 Who, having received such a charge, thrust them into the inner prison, and made their feet fast in the stocks. 25 And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.
Acts 16:26 And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one's bands were loosed.
May God add His blessing to the study of His word. “Good night” and God bless!
