Grace preaches her final sermon at St Luke's as she completes her role as curate here and moves on to become vicar of St Luke's, Leagrave, Luton.
Grace delivers a specific message for the people of St Luke's, Watford from Ephesians 1.
The power of Jesus Christ, dunamis, is available to all of us. It is perfected in us when we are powerless.
Do we know this power of Christ? Do you want to know this power? We can only know this power of Christ when we encounter and experience Him.
The other reading used in this service was Matthew 3:13-17.
