Lots of people have commented on how useful they found the discussion Catrina and I had last Sunday on the Biblical basis of marriage, and us talking about some of what we have learnt about practically building a marriage which will last a lifetime. If you missed it you can find the podcast of what we had to say here.
For anyone who wants to look in more depth at what they Bible has to say about marriage then I want to strongly recommend Tim and Kathy Keller's book "The Meaning of Marriage". Whether you're single, in a marriage which is struggling or in a marriage which is going well then you'll find teaching here which will both give you a fresh perspective on God's view of marriage, and some great practical insights on how to build a strong marriage. I can't recommend it strongly enough.
If you do get a copy and read it I'd love to know what you make of it.
