I live in a community where not everyone gets on well with each other. I imagine that is true of every group of people. I witness various groups , some weeks certain people are friendly, then they fall out. This is a human failing that sadly happens all over the world. No wonder we have wars and political unrest. God knows the state of the human heart and our likelihood to be in disagreement, which why Paul needed to write in 1 Thessalonians 5:13 ‘Live in peace with each other.’ and again in verse 11, ‘Encourage one another and build each other up, just as in fact you are doing.’
Disagreements on a small scale lead to upsets, loneliness and sadness., on a national and global level they can lead to war and great loss of life. On a personal level we need to be a friend and accept friendship. The letters in the New Testament are full of Christian advice in this matter. We are all living on this planet together. We need to realise that if we are feeling lonely or sad, so might the other person and we can treat them as we would wish to be treated. As Psalm 133 says ‘How good and pleasant it is when brothers live in harmony.’ Psalm 133:1
