There are 3 types of Communication: with Yourself, God and others.

3. Communication with Others
Right communication with your own self will help you to communicate right with God. It is only then that you will be able to love another human being as you love yourself. Anyone who doesn’t know him or herself cannot love another human being, because they will see life through the tinted glasses of self interest, emotions and insecurity casuing injury to people and relationships. Thus, the degree to which you know yourself is the degree to which your communication and interaction with God and others can flourish.

Luke 10:27-28
And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. And he said unto him, Thou hast answered right: this do, and thou shalt live.

The principle of success in any form of relationship does not depend on physical, sexual or emotional compatibility but rather on the communication skills of the individuals involved and their commitment to the use of communication to advance or manage their relationship.

Any two people can work together if they can achieve agreement.  The reason why relationships fail is because people are not skillful in achieving this or are often too self centered or even ignorant on the issues of communication.
