One of the greatest ways to celebrate your spouse is in the presence of their creator.  I am very serious about this.  Spend some time on a regular basis just praising God for your spouse. You can celebrate just the fact that God gave them to you.  You can praise Him for how blessed and different you are because they are in your life.  Praise God for their attractiveness, sexuality, personality, humor, friendship or any other attributes your want to highlight to the Father of your spouse.
