Kiruv
From Halachipedia
Kiruv or Kiruv rechokim consists of religious outreach to non-observant Jews. In the Torah, the concept of religious outreach is termed Tochacha (reproof) and the commandment is given to the individual Jew to “surely rebuke your neighbour”.[1] The concept of Kiruv denotes the necessary compassion to ensure the success of the reproof.[2]
