Christian festivals help people to remember the story of Jesus' life. They are also times to give thanks to God for His blessings and to celebrate the saints.
Harvest refers to the time during autumn when farmers traditionally brought in the crops that supplied their community through the year. Although our food today is more likely to come from the supermarket, Christians believe it is still important to remember God as creator and thank Him for the good things He provides.
Many churches do this annually at a Harvest Thanksgiving service. At this service, members of the congregation might bring gifts of food and flowers to decorate the church building as a sign of their thanks to God. These gifts may later be taken to needy or elderly people in the neighbourhood.
