I question the usefulness of treating “Jesus our brother, kind and good” and “Jesus, our brother, strong and good” as separate hymns. If there were any reason to think that it made a doctrinal difference, I might say okay, but I find it hard to imagine that anyone who sings that he is kind is denying he also is strong or vice versa. If I don't hear otherwise, i'll go ahead and merge them. There are six instances of each first line, although one of the “kind” ones has been miscredited to “strong” so it looks like strong is in the lead 7 to 5; the only question is which to use, whether to look primarily at recent usage or at historical usage.
