A blessed man (Psalm 1)

A blessed man is one who meditates on the law of God every day. At the time it was written, the law would have been the Mosiac code. For me, it is difficult to see how meditating on the Mosiac code would leave me blessed. But I think meditating on the law of Christ (love God more than yourself and love your neighbor as yourself) every day would lead to blessing. At the very least, I think it would be an interesting spiritual exercise.
