What does God want from us? He does not want mere hymn singing, although that is fine. Nor does He want only prayer, although that too is fine. He does not simply want our attendance, although that is fine. What He wants, first, is a thankful heart. That is what He seeks, a thankful heart. “Sacrifice thank offerings to God, fulfill your vows to the Most High” (Ps 50:14).
Each one of us is to offer to Him the sacrifice of thanksgiving. A sacrifice is something into which we put effort; it costs us. Have you ever asked yourself why the Scriptures stress thanksgiving so much? Both the Old and New Testaments emphasize that above everything else, God wants thankfulness.
We are told to “give thanks in all circumstances; for this is God’s will for you in Christ Jesus” (1 Thess 5:18). Why is this? It is because thanksgiving only comes as a result of having received something. You do not give thanks until you have received something that comes from someone else. Therefore thanksgiving is the proper expression of Christianity, because Christianity is receiving something constantly from God.
God doesn’t want fake thanksgiving. God doesn’t want you to go around shouting,
Hallelujah! I’ve got cancer! But there is something about having cancer to be thankful for. That is what He wants you to see. There are aspects of it that no one can possibly enjoy, but there are other aspects that reveal purpose, meaning, and reason. God wants you to see this–what He can do with that situation and how you can be thankful. Thanksgiving is the first thing He wants in worship.
The second thing is an obedient will: “fulfill your vows to the Most High“. Notice the kind of obedience it is. It is not something forced upon you; it is something you have chosen for yourself. A vow is something you decide to give, a promise you make because of truth you have seen. When we have received God’s revelation and vow to obey His commands, then He expects us to act on it obediently. We can expend much energy complaining, blessing no one. How can we re-focus our thoughts so that we have an attitude of gratitude no matter our circumstances?
Lord, I offer to You right now the sacrifice of thanksgiving. Thank You that You are at work for good both in me and through me. Grant that I might obey your truth out of a heart of gratitude, keeping in mind Your sacrifice for me, who deserves none of Your grace and mercy. In the precious name of Jesus, amen.
