What will happen to Christians who try to remain faithful to God by themselves?

When we feel that we are all alone without friendship or support from others, we may become discouraged and want to give up. That’s why the prophet Elijah, under death threats from the wicked queen Jezebel, grew despondent and ran way to the desert and mourned that he was the only one (he thought) that loved and served the true God (1 Kings 19:9-10). When Jesus sent his disciples on their preaching ministries, he sent them out “two by two” for a very good reason. They needed to help and encourage each other. That’s why the apostles worked in teams and Paul traveled on his missions with a partner or partners (Acts 1:13-14; 3:1; 9:26-27; 10:23; 11:30; 13:2; 15:39-40; 18:18; 20:2-6). Even Jesus, the Son of God and our Savior, wanted the companionship of his disciples (as in Mark 3:14). When they slept on the darkest night of his life, he asked them, “Could you not watch with me one hour?” (Matthew 26:37-40). Paul felt the same need for human companionship. In the closing days of his life, he desired that his friends come and be with him (2 Timothy 4:9-20).

God made us to live in families and communities. In the beginning, he said, “It is not good for man to be alone” (Genesis 2:18). That applies to all the areas of life. The writer of Ecclesiastes addresses our need for each other:

Two are better than one, because they have a good reward for their toil.  For if they fall, one will lift up his fellow. But woe to him who is alone when he falls and has not another to lift him up!  Again, if two lie together, they keep warm, but how can one keep warm alone?  And though a man might prevail against one who is alone, two will withstand him—a threefold cord is not quickly broken. (Ecclesiastes 4:8-12)
