What is the most important commandment?
To love God and your neighbour (everyone) as yourself; to treat everyone with respect and dignity just as you would like to be treated by others.
Jesus told us to love one another as there is no greater commandment than this: it embraces the Ten Commandments so succinctly. As it is increasingly difficult to obey, we use the strength of our Lord Jesus Christ to aid us in the task.
We agree with the supreme importance of the first commandment: to love God. Without this the Christian faith is merely lip-service. We try to demonstrate this through our actions in daily life, which for many of us as Christians should be an expression of loving God and our neighbours.
God so loved the world that he gave his only Son, so that everyone who believes in him [with love] may not perish but may have eternal life.” John 3.16, NRSV
In summary, what Jesus told us is the best answer: to love the Lord your God with all your heart, with all your mind and with all your strength and you shall love your neighbour as yourself.
