A brother writes us from Armona, Cal., asking us what to do with a chain-letter. He received it, saw no harm in it, and sent it on. The one to whom he sent it returned it, and now he does not know what to do with it. It will cost $9.16 to return the chain-letter to the originator, besides all the cost of paper and postage. Now, what shall he do?—Let it drop right there. Unless postage, at least, is enclosed, no one in this world is placed under obligation to reply to, or to write, a letter, simply because he is asked to write. There are business letters, friendly letters, and letters involving mutual obligations, which demand reply; but no chain-letter that we have ever seen demands the writing of any other letter, unless mayhap, a good missionary letter to the one from whom you received it. This chain-letter in question, “No. 458,” is a harmless sort of one; it is a request that the individual will pray earnestly, and ask some one else to, that God will abundantly bless all efforts of missionaries, and raise up more missionaries, and that the chain of prayer may not be broken. Now, all this is good enough, but effectual prayer does not come in that way. Every true Christian is burdened for some other person or persons. If he labors as the Spirit moves, his burden will grow. God will give him travail of soul for others’ birth. But if he is not where God can impress his heart, we have no faith in his chain-letter promises, or any other mechanical means.
