To always be in this high state of consciousness would be where no evil could befall one. David knew this in all his varying moods. Sometimes his praises would be one of adoration. Other times, thanksgiving. Other times almost a begging and beseeching of the LORD to help him in all the many difficulties in which he found himself.
Praise is one of the surest ways to keep from getting slothful in spiritual life.
It is so very, very easy and one of the surest ways to keep from getting slothful. Everyone responds to praise. How their little faces light up when they are praised for some small thing. They will run and do more. They want to help and they want to respond to that praise.
