Here is a perfect example of 'believers'.
Am I to agree/speak in humility that even though we disagree, we both love Jesus/or stand for the truth? I am a believer in a completely different Gospel,The Gospel of the Grace of God, not The Gospel of the Kingdom.
In many cases we have a different God, a different Jesus , a different salvation .. we are poles apart ... we can talk.. debate.. but we will never have true unity
