Oftentimes a person can feel the emotion of loneliness. This can come from (among other things) traveling away from home, a separation from a loved one, or being stressed and anxious in life. One thing God tells us over and over in the Bible is we are NEVER alone. He is with us always. That is a truth that is good news.
Joshua 1:9 "Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go."
Matthew 28:20 "And behold, I am with you always, to the end of the age."
Isaiah 41:10 "Fear not, for I am with you; be not dismayed, for I am your God; I will strengthen you, I will help you, I will uphold you with my righteous right hand."
