In order to remain in the essence of oneness of the Body, we must reject our self-choice and self-preference. Even in taking the cross we must be careful not to choose the self, to elevate the self in our nothingness. Christ living in us is what brings us up. This is not a mental practice of being dead, but the enjoyment of Him. We love Him, not our death. Not "I die" but "He lives". Our death is appreciated and realized when we enjoy and live Him.
And finally, here are some principles of the Body:
If we live in the body, we will experience the protection of the Body.
We should always consider the Body, care for the Body, honor the Body, and do what is best for the Body. (1 Cor. 12:23-27)
