Philippians 2:8

‘And being found in fashion as a man, he humbled himself, becoming obedient even to death, yes, the death of the cross.'

In the same way as Jesus had done they were to choose the way of humility, deliberately electing in their minds to be ‘crucified with Christ' (Galatians 2:20), to as it were die with Him on the cross, reckoning themselves as dead to sin. This was to be the end of all selfish ambition, of any sense of superiority, of any desire to be exalted over others. They were to die to themselves and their own ways and ideas and ambitions in order that they might become true servants of God and live only unto God, in togetherness following only His ways and desires and ambitions, something which would of course deeply affect their relationship with one another.
