'Give thanks and praise to the Lord, and I will feel all right.' So goes the Bob Marley anthem, One Love. Who could disagree, other, perhaps, than a few ardent atheists? But even the most embittered sceptic would have to concede that a sense of awe and appreciation is a very healthy thing to have. What does it matter whether this is directed towards a deity, an imaginary personification of creation or simply the sheer mystery of the unknown and the unknowable? Reach for the spirit of One Love today, and it will reach out to you.
