Are there any Christian housewarming gifts I can get a divorced dad?

I don't know about best gifts, but you can give him gifts that have scriptural passages on or in them. It could be a shirt with “Never Stop Praying” written on it. You could give him Bibles and books of Bible stories for the children. It could be a wall paper or poster with Ephesians 5:20 (Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ) written on it. It could be a Crucifix wall cross.

When looking into Christian symbolism, water is generally accepted as the symbol for rebirth. For a divorced parent, rebirth is part of his life now and the path moving forward. Housewarming is such a special opportunity to give a gift that will contribute to the atmosphere of the home for years to come. Think about some artwork or perhaps framed scripture affirming this theme.
