Madam, alhough I am a lifelong Christian (of the sort who actually READS the Bible and tries to fit my life to God’s ideal rather than the reverse of that), and one who is quite familiar with the line from the apostle Paul, your expression of that thought struck me and made me stop for a moment. I now plan to write a poem based on this line, with your permission, crediting you as the prompt. The first three lines have already written themselves:

Learn the tree by seeing the fruit.

Never mind what’s at the root,

for branches can be grafted in…
