Can't I follow Him alone?
Yahweh has not placed just one person on this earth because it isn't good for us to be alone. He said: "It is not good for the man to be alone. I will make a helper suitable for him." (Gen 2:18) And that is the truth about everyone He has placed us together with. People are there to help us grow up right and to teach us and to burn away our wickedness.
In particular we should seek out fellow believers when we come to Yahweh, because as the term 'born again' indicates, we are as little babies who need to grow up in a family. And people are never too old to be members of a family, they just become older sisters or brothers or parents themselves with time, responsibilty and loving understanding. We all know that this is important in physical life but it is just as important in all areas, also psychologically and spiritually.
