this hymn is under the category of consecration - all on the altar.
i really appreciate the chorus, which says
"is your all on the altar of sacrifce laid?
your heart, does the Spirit control?"
we have this indwelling Spirit, which always seeks to rule, regulate and restrict our conduct, so that we can become a proper testimony and expression of the Lord in our daily living. but most of the time we are so rebellious, not willing to obey the inner leading of the Spirit, which disqualifies us to be the children of God. therefore, we need to receive the abundance of grace so that we can reign in life (Romans 5:17), which means that we allow the Lord to reign and rule within us, which equals to let grace reign in us. In this way, we will be enabled to lay all that we are, all that we have, on the altar, and to let the Spirit fully control our heart.
