“How great Thou art” is one of the best loved hymns, and I believe there is a reason for that. It is the song of all of God’s children. The writer of the lyrics was doing his best to describe just how great God is. God is so great, our words are really not adequate to fully express the greatness of His love, His mercy, His power, and His holiness. The writer used nature as a way to describe the greatness of God. He also used the death and resurrection of God’s own son to describe the incredible love, mercy, and greatness of God towards His children. So, as the song tells us, when we reach heaven (our home) and see Him (the one who made all things possible), we will bow down, and with great joy sing and tell of all His greatness.
