The apostle writes (in most Bibles):
a door was opened for me in the Lord,
So in English, this is more suitably translated as:
a door was opened for me by the Lord
Or, since this verse seems to be using Lord as a euphemism for the Divine Name of God (see the link in the text for details), our translation says:
Jehovah had opened a door [of opportunity] for me there.
