I want to stress the importance of all work, the importance of your work in God's sight.
But let me say at the start that you will always be more important than your work and that your character matters to God more than your achievements. In a society which has little to say about the first and endlessly exalts the second, this is a vital Christian perspective.
Put another way, some of the greatest achievements are unsung by the world because they have been made in the realm of the spirit. However, Christian people should have a theology of work.
