More than 1,000 people saw in the new year at HTB Brompton Road at the church's annual New Year's Eve Prayer and Worship event.
The event was led by HTB Prayer Director Pete Greig who announced the launch of a new national prayer initiative called Kingdom Come: UK.
KC:UK is a joint initiative of Alpha and 24-7 Prayer that aims to have a year of continuous prayer in churches across the UK and Ireland in 2012.
It was launched at midnight with two prayer groups starting a week of continuous prayer, one in the most northerly town in Britain, Thurso and one in the birthplace of 24-7 Prayer, Revelation Church in Chichester.
The HTB party started with worship led by Ben Cantelon followed by HTB Prayer Director Pete Greig opening up the mic to anybody who wanted to share a story of answered prayer over the last year.
Several people came up and shared stories ranging from God interceding to help those on a GAT to miraculous healings.
HTB Curate Bill Cahusac led a time of prayer and asked for people to think about what they should thank God for in 2011.
As midnight drew closer those in attendance began to pray for the nation.
At midnight balloons were dropped from the ceiling and party poppers were popped amid cheers.
