Everything the Holy Spirit does bestows grace upon us. Sacraments, like the Church, are both visible and invisible. In every sacrament there is an outward visible sign along with an inward spiritual grace. They are moments we experience in which God reveals Himself to us and imparts His grace upon us. Through marriage, God (through his representative) joins a man and a woman as husband and wife. Marriage is not simply a social institution or legal contract. It is an eternal vocation of the Kingdom of God that continues from this life into the age to come. The Holy Spirit calls a husband and wife to share their Christian life together in all respects.
