The fountain of eternal life comes directly from God. All of us who have believed that Jesus is the Son of God, that He died, was buried and was resurrected from the dead have experienced this new birth. All of us who have decided to follow Jesus have been instrumental in sharing this fountain of life with others. Our names have been written in a Book of Life.
God loves, establishes, preserves, and supports us. In that sense of purpose that we are His there is incredible life. Singing and dancing are natural parts of our expression of life for everyone that puts their dwelling place in God will experience every source of delight that flows from His fountain.
