I think it is sad that some of our greatest opposition comes from our own church. To many Christins today have forgotten the whole love one another thing, this was not a request from Jesus it was a command. As a Sunday school teacher for our teenagers I found that many church members get angry and try to tear down good things if they are not getting attention or don't understand the message. Our youth minister has been accused of calling students demons because people take things out of context.
Don't be discouraged, James is the place to be when dealing with this. I think sometimes our best witnessing can be to Christians who don't understand the power and authority of Jesus. Ther are too many "fire insurance" Christians out ther that are looking to worldy things and there own glory. Don't misunderstand, I am far from perfect, I simply feel if I am a truck technician I should follow my bosses rules and be the best I can, if I am a Christian I should follow Jesus' rules and be the best Christian I can. Don't give up on them, love them and pray for them. The hardest thing I have done is pray for members of my congregation that irritate me. I have had God tell me I am just as irritating to them. We are all different and have different purposes in the body of Christ.
A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.
