This is an idea I found in an article concerning the way churches and ushers deal with people who attend church infrequently. I won’t bother linking to the article, since I find it prosaic and dull. I don’t know whether churches are better with or without ushers, as it is not the way in Europe.
If you want someone to come through a door, unlock it.
Haven’t I heard that one somewhere before? Hmmm…

Rev. 3:20: Behold I stand at the door and knock… and the painting “Love Locked Out” by Anna Lea Merritt (1881) produced this poem:
Love Locked Out
Iron clad and solid door,
firmly locked and barred within,
denying entrance to the house of warmth,
of merriment and righteous joy,
the place of light and food and celebration,
the like-minded gathered at their banquet,
their rejoicing in their goodness,
vaunted pride in knowing their great worth,
only slightly bothered by the sound of knocking,
or the cries of sorrow from without.
Naked, love is standing in the cold,
hungry, naked, crying in the chilling breeze,
knocking, knocking, ever knocking,
bruising knuckles on unyielding plate,
knocking, knocking, crying out in pain,
proclaiming love without conditions,
begging humbly for admittance,
begging, begging, never heard
never welcomed,
love locked out.
Love locked out,
beauty always seeking entrance,
arms that offer warm embrace,
a sweet high voice of deep endearment,
wanting nothing but the chance to love.
Iron clad and solid door.
firmly locked and barred within
by the satisfied,
self-satisfied,
proudly preening righteous ones,
who need no love, who have enough,
and know that they are better,
finer, worth far more,
than those they have locked out.
Love locked out,
naked, cold, ignored,
knocking, knocking, knocking,
calling, calling, calling,
“It’s you I love, you I love,
won’t you let me in?”
