My friends, you do not have to do this alone. The Holy Ghost, who is a member of the Godhead, will be your companion, guiding and directing you in quiet yet perfect ways. Take advantage of that counsel that reaches far beyond good ideas and worldly wisdom.
Elder Ronald A. Rasband, "Be Not Troubled", Deseret Book 2021
Every single one of us have been born with the light of Christ, sometimes known as our conscience. We all know that done things are just plain wrong. That...is the light of Christ. Likewise, we all have the opportunity to feel the Holy Ghost, guiding us to truth, protecting us. His job is to testify of Christ. After His job is, done, He leaves.
However only baptized members have the gift of the Holy Ghost to be with us 24x7 if we are worthy of His companionship. 24x7. All the time. Every second. We have this gift because of and through the authority and power of Heavenly Father, even the Melchezidek Priesthood.
But, because we are mortal, we do things that cause Him to temporarily leave. He cannot abide evil or wrong. He cannot exist when we willingly choose the darkness.
But...and this is key....even if we are surrounded by darkness, enveloped even, He will be our companion out of the darkness, if we want and act accordingly to have His companionship.
