God is real and alive and will not let a son be alone. It is feelings that get in the way. condemnation is a trick to keep us out of fellowship with the Lord. The priest in the O.T. could only go into the Holy of holies once a year. They knew that God was a very present help in time of trouble.
The Holy Spirit who is God, lives in those who receive him. He is the comforter. Jesus can be there all the time because he made the priesthood to be changed so he could be our great high priest. see Hebrews 7:24-25. Loneliness is a feeling-not a absence. Whether we (think) or not he is there within us.
He is a friend who sticks closer than a brother--he lives inside us if we are filled with his Spirit. Sin and fleshly living blocks the fellowship till repentance.
A personal experience I had years ago. While driving to work on a day where there was snow on the ground, I was heading down a hill. You either turn right or left. in Front was a cliff. It was a big drop which at the bottom was a large brick house. The road I was on was covered with ice and you were driving down a hill. No guard rail?? I went into hydroplane. I hollered the name of JESUS. There was no street under me it was all ice. All of a sudden I heard road under me it sounded rough as though I was on pavement. my car stopped at the stop sign. There was no pavement just ice. God caused me to stop and saved my life as the cliff would bring death. Yes he was there and his name saved my life. I turned left and arrived at work. Thank you Jesus.
