Travelling the world, crossing time zones, and generally being tired, can wreak havoc on relationships. However, it is worth persevering as we are made for connection. One connection that I find particularly important, is connecting in with Christ and being a member of a church.
Attending church can be a challenge if travel means you are away from your home city. Modern technology does however come to the rescue. My wife and I have been fortunate to find a great church in Wellington, New Zealand, that stream their services live. When we are in New Zealand, we attempt to go in person (especially if we are in Wellington), but when we are elsewhere, we nearly always connect in each week. We live in the UK, on the opposite side of the world to New Zealand, so we stay up late to ensure we receive the latest talk, and remain connected in our faith. We also have a local church which is great.
