God gives the gift of the single life to some and He gives the gift of the married life to others. (See 1 Corinthians 7:7)
So, if it is God who has given you the gift of being married, then the spouse He gives you will be the right one, the person you meant to be with and the marriage will never end up in divorce!
Because what God joined together no one will be able to split apart! (See Matthew 19:6)
