 and again in October. For two days, we have the opportunity to listen to prophets and apostles and other inspired leaders as they share messages about living the gospel of Jesus Christ and trying to become better people.
We talk often of continuing revelation in The Church of Jesus Christ of Latter-day Saints. General Conference is a time when such revelation can be witnessed. Personal revelation can also be received as we come prepared, prayerfully seeking personal guidance to our questions and concerns.
We look forward to this wonderful weekend!
-There are many ways you can experience General Conference.
-Conference means more when we prepare for it. Here’s a list of suggestions to prepare for the messages we will hear.
-For younger children, it can be helpful to have activities to help them listen and identify themes and topics that are addressed. See the Church’s Conference Activities for Children page, which includes both online activities and pages that can be printed. LDSMediaTalk has included information about Conference activities in various languages.
-Read what one family has done to make General Conference memorable.
I am so looking forward to conference this weekend. I always seem to get answers to numerous questions or concerns as I listen.
Heavenly Father addressed our missionary son’s concerns thru Elder Holland’s talk today — our missionary’s been worrying about what he should do when he comes home. Tears streamed down my face as I heard how Elder Holland faced his return from his mission and found answers to his worries.
Heavenly Father hears and answers prayers!!! Again and again, and again!
Hospitals have embraced UVC lights as a cleaning tool for years, using large, industrial-grade machines to decontaminate wards. It has been proved the UVC bulb is effective and widely used for years.
The most affordable UV light sanitizer wand. Its lightweight design makes it easy to carry. The UV light is powered by 4 AA batteries. And the UV safety switch ensures your skin and eyes are protected during use.<reponame>phetdam/npy_openblas_demo
