‘Sacrifice thank-offerings to God,
Psalm 50:14-15
fulfil your vows to the Most High,
and call on me in the day of trouble;
I will deliver you, and you will honour me.’
The fellowship offering
11 ‘“These are the regulations for the fellowship offering anyone may present to the Lord:
12 ‘“If they offer it as an expression of thankfulness, then along with this thank-offering they are to offer thick loaves made without yeast and with olive oil mixed in, thin loaves made without yeast and brushed with oil, and thick loaves of the finest flour well-kneaded and with oil mixed in. 13 Along with their fellowship offering of thanksgiving they are to present an offering with thick loaves of bread made with yeast. 14 They are to bring one of each kind as an offering, a contribution to the Lord; it belongs to the priest who splashes the blood of the fellowship offering against the altar. 15 The meat of their fellowship offering of thanksgiving must be eaten on the day it is offered; they must leave none of it till morning.
Leviticus 7:11-15
Under the Law, a man could simply say he was thankful, but if he was really thankful, he also brought a costly thank offering (Leviticus 7:11-15). Today, while God is no longer interested in animal sacrifices, a truly thankful believer will present his body to God as a living sacrifice. This kind of sacrifice costs us our time, our labor and our money, but it is only “reasonable” that we afford Him this service (Romans 12:1) in light of all that He has done for us in Christ.
Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship.
Romans 12:1
A sacrifice is something precious, of great value, given out of love and devotion to God. If it costs you nothing, it is no sacrifice. The sacrifice God wants is you… your body, your time, your very life. According to the rest of the chapter (Rom. 12), the sacrifice you offer will be inline with your spiritual gifts. Yet there are so many tasks to be done in the church that anyone can do, and that do not require any special gift at all. Most churches respond by squeezing the 20% of active, hardworking people for even more sacrifices. This is ineffective for the long run, and it means that the other 80% will have little to show their Lord for their lives when the time comes for showing. Offer yourself to Christ, give Him your whole self, and ask, “Lord, am I doing all I can to turn the wheel of the church? Am I fully consecrated to you?” I believe God wants to do great things in your own church. May He do them through the dedicated service of each one of you!
