Can "If" really be compared to Christianity considering that Rudyard Kipling was an agnostic, and then later joined freemasonary?

Nowhere in the poem does Rudyard Kipling say the word
"God".  I do not believe that he was trying to give Christian values to anyone.  He was
saying, if you do these things, you will be a good person. Good people exist outside of
Christianity.  There are many good people who are Jewish, Buddhist, Islam and other
religions. Free Masons believed in a Supreme Being, but they did not have to state what
that Supreme Being was. They accept people from all religions.(See link). There is not
anything anti-Christian in what Kipling says. There is also nothing that says a person
has to be Christian. Although many Christian values can be found in this poem, he has
just kept religion totally out of it.  He was trying to tell young people how to live a
good life.
