I believe marriage is a relationship of 3. The first, and most important relationship, is your lifelong vow and commitment to God. The second is to your spouse. As long as the first one is in place the second one naturally occurs.
Marriage is not about percentage (50/50 or 100/100) it is a commitment. To be completely committed, means the two become one. Success occurs when a single unit (a committed marriage), moves deliberately toward a single goal (dedication to God). This heart-felt, loving commitment becomes a grateful celebration to share together each and every morning.
