Is tithing required in today Christians?

In Leviticus 27:30, it state that a tithe of everything from the land, whether grain from the soil or fruit the trees, belongs to the Lord. Mosaic Law required to the Israelites that give tithe God. However, it is not required for today Christians. Because we are not under the Old Testament Law anymore but we are under the New Covenant. Many People are arguing and debating about tithing. Some people say that tithing is only an Old Testament Law that does not need to follow as believers under the New Covenant. And some people say that it just a relevant to New Testament Christian as it was in the Old Covenant.

Can person be blessed without tithing?
Some people say that we will not be blessed if you do not tithe. I think it depends on the person. 2 Corinthians 9:6-7 states that “Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.” Person can be blessed without tithing. But, if person plants few seeds, he will get a small crop and if person plants generously will get generous crop. Also, God loves a cheerful giver, not under compulsion.

The Israelites under the Old covenant, their blessing was a physical one. However, Christians in the new covenant have much better blessings –its spiritual one. We blessed through the atoning sacrifice of Jesus Christ for us and the gift of the Holy Spirit to us. I think we better give tithing more than initial audience did. Because of we have much blessing than initial audience. However, the important thing is that tithe is not required or must but it is willing. God loves a cheer giver.
