The text tells us that a voluntary sacrifice was when a person
came before God to worship and have fellowship (friendship and
talking) with the Lord. He needed to realise that God is
Almighty and is a Holy God, and so he had to bring a burnt
offering. The shedding of this animal's blood was to cover
his sins. But, one thing set this sacrifice apart, for the
animal had to be burnt up by fire.
For us, dedicating ourselves to God is also voluntary when we
decide to respond to Jesus fully and give our lives to Him.
In Romans 12:1 Paul says:
"I urge you, brothers, in view of God's mercy (unmerited favour),
to offer your bodies as living sacrifices, holy and pleasing to God
Which is your spiritual worship."
God is not satisfied with our second-best. He wants the best
and He wants us to give ourselves entirely to Him. An old
familiar chorus said, "All to Him I freely give".
Are you going to say to Jesus, "You can have a little, maybe some,
perhaps a lot". Or will you say, "Lord take all of my life
as I want to serve You with all of my heart!"
