Psalm 50 God doesn't want.

⁷ Hear, O my people, and I will speak; O Israel, and I will testify against thee: I am God, even thy God.

⁸ I will not reprove thee for thy sacrifices or thy burnt offerings, to have been continually before me.

⁹ I will take no bullock out of thy house, nor he goats out of thy folds.

¹⁰ For every beast of the forest is mine, and the cattle upon a thousand hills.

¹¹ I know all the fowls of the mountains: and the wild beasts of the field are mine.

¹² If I were hungry, I would not tell thee: for the world is mine, and the fulness thereof.

¹³ Will I eat the flesh of bulls, or drink the blood of goats?

¹⁴ Offer unto God thanksgiving; and pay thy vows unto the most High:

What do you think when God tell us these?

Are you feeling afraid or being rejected?

Well to start, in the ancient times, people offer burnt offerings to God for them to be forgiven. The offering (goat) must be the best in your flocks. This is fully disclosed in the story of Abel and Cain. 

But with this context, what God really means with His words He did not want your bullocks, goats and the like?

Is He rejecting His principle before ancient times? or did Cain and Abel are wrong?

Well, I cannot really tell what is the exact meaning or what was God trying to tell us. 

But God shows and testify that He owns everything this world and even us. God shows that he is mighty and King. with our burnt offering, for Him this is NOTHING. Do you think when a carpenter makes a house then sell it to buyer and that buyer will resell it to the carpenter , is rational? The view here, God will get what He wants in this earth coz He owns it. and He doesn't need anyone to return it from Him. 

Hmm, I may not show it logically but the thought is God is the maker and the owner of everything. Being a human, His creation, is not rightful for Him to return something He owns just to be forgiven.

What He wanted a heart that is faithful and ready to sacrifice, and a glorifying heart for God for him to bring back the Glory of God.

Yes, we may have different interpretation but being moved by the Holy Spirit, this is what God wants me to share you this day. :))

How about you? What is your understanding with these passages? God has a lot of hidden words.
