Before I became a Christian Scientist, at moments when I felt quite happy I also had a depressing fear that this present joy would be followed by sorrow or unhappiness.
When a lawyer tempted Christ Jesus with a question about attaining eternal life, Jesus concurred with his questioner's own answer from the Mosaic law: Love God, and love your neighbor.
I was blessed by being raised from birth in a Christian Science home, surrounded by loving and dedicated relatives, and during my childhood I was singularly free from ailments and accidents.
