Genesis 2:18 -- "Then the Lord God said, “It is not good for the man to be alone. I will make a helper who is just right for him."
So why do we think we have to do everything on our own? God meant for us to have fellowship. He created the church so we could teach and support each other. The church did not begin as the institution we now know it as. The first century church, the ones who knew Jesus personally, were simply men and women who would gather together in homes to pray, contemplate scriptures, teach, counsel and lift each other up. They were not the social cliche bible study, they were were fighting persecution from the Roman government and the Jews.
John 15:19 -- "The world would love you as one of its own if you belonged to it, but you are no longer part of the world. I chose you to come out of the world, so it hates you."
You may not believe you have anything to teach others, but I bet God has a different opinion. He created us all unique with different stories and different struggles all to help each other through this difficult journey we call life. We can lean on each other, draw strength from each other and teach each other lessons we have already learned.
