After God, who is the central core pillar to any Christian marriage, there are four important marital relationship foundations. These are:* Self-Esteem - if you don't love yourself you will find it almost impossible to accept love from others.* Friendship - a strong friendship will sustain your marriage even when feelings of love are harder to find.* Laughter - it will improve your quality of life, your health and your relationships* Romance - feeling close to your partner can be the glue which holds your relationship together through the rough patches, but the absence of romance causes a void that problems will easily fill.
