Man’s spiritual life is set forth negatively and positively, inwardly and externally, figuratively and literally. Above all else, it summarizes all that is to follow in the rest of the Psalms, and, for that matter, in the rest of Scripture.
Happy those who do not follow the counsel of the wicked, Nor go the way of sinners, nor sit in company with scoffers.
The psalm views life as activity, as choosing either the good or the bad. Each “way” brings its inevitable consequences. The wise through their good actions will experience rootedness and life, and the wicked, rootlessness and death.
