To this end I also labor, striving according to [Christ’s] working which works in me mightily.
As children, we hated having to go places alone without the security of a parent—like walking into a new school building alone on the first day of school. Little has changed. As adults we still fear being alone—in times of trouble or crisis or discouragement, when facing responsibilities and challenges that only we can undertake. God noticed the unnatural state of aloneness shortly after creating Adam (Genesis 2:18).
There’s another way that little has changed: the presence of Christ with those who follow and serve Him. Before His death, resurrection, and ascension, Christ was always with His disciples. He taught them, modeled life for them, and trained them. After His ascension, His physical presence changed but not His spiritual presence. By the presence of His Spirit, He was with them as much as He had been. Paul gave testimony to this fact more than once (Galatians 2:20; Colossians 1:29). Jesus promised He would be with His disciples (Matthew 28:20), and He was (Mark 16:20).
If you are Christ’s, He is with you in every situation of your life. You never have to go anywhere or do anything alone.
The problem with atheism is having nobody to talk to when you are alone.
