Acts 15 contd - Agree to disagree

I guess we always think of the early church as being perfect. Everyone loving one another, everyone getting along, everyone encouraging one another etc... However in this chapter we find two different things happening. 
On the one hand we have Judas, Silas, Paul and Barnabas going to encourage new Christians in their faith, while on the other hand after encouraging one another we find Paul and Barnabas going their separate ways due to a disagreement! 
If there is one thing we can all agree on, we can never please everyone all at the same time. We are human beings with different opinions and so we need to rely on the Holy Spirit to guide us and to help us to 'be completely humble and gentle; be patient, bearing with one another in love' -Ephesians 4:2
I know that I can't do this without God. There have been many occasions where other Christians have upset me or even let me down, and I'm sure that there have been occasions where I have done something to other Christians that has upset them or let them down too. We need to totally rely on God so that we can be Ephesians 4:2 to others. So that we can encourage one another in love and not tare one another down. Let's get to a stage where we love one another and just want to serve one another. Let's get to a stage where we love one another so much that even when we disagree we can still agree.
