Families grow closer together when you all turn towards him. This isn't just a preacher talking. There was a university study done in 1990 that demonstrated that people highly involved in their faith have the happiest marriages and the most fulfilling family lives. Look it up. Of course that makes sense, because to take the cross of Christ seriously in your life means that you accept sacrificial love of Jesus Christ for you and it changes you, it leads you to live out a life of sacrificial love for others, especially to those closed to you.
Sacrificial love leaves all pettiness and division behind and builds strong community.
In closing, just a word to those of you who are in a marriage where your husband would never pray with you or share your faith, or in a family where your parent knows nothing about sacrificial love, but only knows about their own addiction, or loneliness, or hurt that still devastates them from their upbringing, or anger and violence. You can still get what you need to- the nurture, the unconditional love, the trusted person that will not walk away. And offering a wing for you to nuzzle under. Open up to Him. Let him care for you.
