Well, that’s a good question and not easy to say in a few words.
It’s about a God of power and love, a God who created the world in which we live and who has remained involved with creation ever since. This God we call Father, who with the Son and the Holy Spirit makes up a Trinity of love.
Although many people turned their backs on God and forgot the ways of peace and justice, God never forgot us. He sent his Son, Jesus, who was born into our world and lived a fully human life, teaching people about the ways of God and asking them to return to the living God.
Jesus was often vilified for his message, and in the end crucified publicly between two self confessed criminals, though he was innocent of any crime. But that was not the end. Three days later he was resurrected from the dead and lives, never more to die, in all time and place.
Christians believe that by his death for each of us, the way was opened for us to know, worship and follow God, through the power of the Holy Spirit, to be the people that God always intended us to be and to live a life of praise, service to others and thanksgiving to God.
Sometimes we get it wrong, but God is a God of forgiveness and mercy - which is just as well!
