I will not leave you orphans, I will come to you. John 14:18 NKJV
Some writers have identified the torment of hell as total isolation.  Drifting forever completely cut off from others and from God. Alone. Always and forever, alone. Conversely, the promise of Jesus is to come to us  dwell with us  and never, never leave us alone.  His very name is Immanuel: God with us! 
The contrast between these two concepts is startling and given a choice we wonder why anyone would ever choose loneliness? But we do.
We choose to be alone when we disobey. Sin is like a dimmer switch. Slowly, one act of disobedience at a time, our awareness of God’s fades until we no longer sense His presence. We feel alone.
We choose to be alone when we let the busyness steal our time with Him. Life is a pressure cooker and clocks can be cruel task masters. Unless we intentionally plan time alone with God and discipline ourselves to keep that schedule, moments turn into days then weeks that we have spent no significant time with Him. We feel alone.
We choose to be alone when we refuse to be silent before Him. Because God is our source and our needs are many, too often we spend the precious moments with Him reciting a laundry list of complaints and requests. When we’ve check off the last item, we dust our hands and race back to life in the fast lane and wonder why we feel alone.
The good news is that our feelings to not shape reality; truth does. And, the truth is Jesus’ promise that He would not leave us. We do not face the world alone. Indeed, we do not face a single day or moment without Him. He has never left us orphans and never will.
