When Jesus told His followers to deny themselves, pick up their crosses, and follow Him (Luke 9:23), He was telling us to put to death our insistence on living for ourselves and start living for Him by serving others.
Loneliness is something that happens to all of us. The important thing to remember is that it is a normal feeling. Can you imagine how lonely Jesus must have felt at times? Especially closer to his death? He was deserted by all of his disciples, betrayed by one closest to him. He completely understands how you feel. Staying positive will help keep the enemy's lies and feelings of loneliness from taking over.
The Ascended Christ said to the church at Laodicea, “You say, ‘I am rich, have become wealthy, and have need of nothing–but you do not know that you are wretched, miserable, poor, blind, and naked." Reality is often far different from what we want to believe, aspire to, or advertise. Dare we ask the Heavenly Father to tell us the truth about our own church?
