No doubt that these liturgies contain meaningful statements while the hymns are someone’s inspiration and experience. The question here is not about the spiritual richness of the liturgies and hymns but how it is being sung by the believers.
David says in Psalm 31: 21-22 that he became fearful and was afraid that he had gone far from Him. Similarly we also face this fear many times in our lives and become worrisome and don’t get justice hence, all our work gets spoiled. David says that he was not of any use but still God showed His mercy and gave him victory. God, whether we believe in Him or not, whether we love Him or go far from Him, will be with us and never leave us alone.
