The simple answer is absolutely nothing other than to observe and listen with an open mind.
If you have never been to a church service before it can feel quite intimidating to walk up the long path to our church door and walk through it for the first time. But please don’t worry we will be there to welcome you and to help you. All we ask is that you come with an open mind and leave the rest to the ‘Holy Spirit’.
The very fact that you are thinking of coming to church probably means that the ‘Holy Spirit’ is already ‘on your case’! But don’t expect to see Him in a column of fire on the altar when you arrive but do expect to feel the ‘Love of God’ reflected in the people you meet, and when you do, your courage in taking that first step across the threshold will have been well rewarded.
