PORTLAND — Jehovah’s Witnesses will hold their district convention at the Cumberland County Civic Center this weekend.

The three-day convention, “Safeguard Your Heart,” is expected to draw about 5,000 Witnesses and non-Witnesses. It began at 9:20 a.m. today. It will continue Saturday and Sunday at 9:20 a.m. each day.

A news release from organizers says the “program promises a fresh examination of biblical references to the figurative heart. Through lively discourses, dramatic Bible readings and presentations, and even a live play, program parts will emphasize how protecting the figurative heart will enhance one’s spiritual well-being, family life and happiness.”

Over the past several weeks, Jehovah’s Witnesses have extended personal invitations to individuals throughout Maine, New Hampshire, Vermont and Massachusetts to attend.

The daily themes and titles of program parts are based on passages of scripture, including 1 Samuel 16:7, 1 Chronicles 28:9 and Matthew 12:34. The convention theme, “Safeguard Your Heart,” is based on Proverbs 4:23. Strengthening one’s spirituality will be the focus of the program.

There is no admission fee. Conventions of Jehovah’s Witnesses are supported by voluntary donations.
