You clearly don't know the correct understanding of the scripture. Malachi is always being misquoted. Malachi is not speaking to people who haven't given as robbing God. He is speaking to the leaders who stole from the tithe already collected and calls them out in chapter 2:1. "And you oh my priests". You cannot call it a tithe until it has been collected and you cannot be robbed from something that doesn't yet exist.
The tithe was a taxation on landowners in Israel. Not everyone had to pay it. Yet is gets preached as if everyone is bound by it when it was the old testaments method of income and we have now been given a new testament method which is everyone giving as they have to share. I'd like to see your author teach on that as it is the scriptural teaching for the church. You cannot expect the new testaments blessings when you hold yourself bound by the old testament practices. Perhaps you should do a detailed study on tithes. Abraham did not give 10% of his wealth away. he gave away 10% of the spoil of battle. This topic is always twisted and taught incorrectly.
The Tithes belong to God & God alone, for a purpose
2 Chronicles 31:6 And
concerning the children of Israel and Judah, that dwelt in the cities of Judah, they also brought in the tithe of oxen and sheep, and
the tithe of holy things which were consecrated unto the LORD their God, and laid them by heaps.
Leviticus 27:30 And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree,
is the LORD'S: it is holy unto the LORD.
Deuteronomy 14:23 And thou shalt eat before the LORD thy God, in the place which he shall choose to place his name there, the tithe of thy corn, of thy wine, and of thine oil, and the firstlings of thy herds and of thy flocks;
that thou mayest learn to fear the LORD thy God always.
Numbers 18:26 Thus speak unto the Levites, and say unto them,
When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the LORD, even a tenth part of the tithe.
The purpose of the Tithes was to fear God,an Holy offering and an inheritance for the Priests
Every person had to offer their Tithes
The reason why the people robbed God was
Malachi 1:6-14 A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear? saith the LORD of hosts unto you, O priests, that despise my name. And ye say, Wherein have we despised thy name? Ye offer polluted bread upon mine altar; and ye say, Wherein have we polluted thee? In that ye say, The table of the LORD is contemptible. And if ye offer the blind for sacrifice, is it not evil? and if ye offer the lame and sick, is it not evil? offer it now unto thy governor; will he be pleased with thee, or accept thy person? saith the LORD of hosts. And now, I pray you, beseech God that he will be gracious unto us: this hath been by your means: will he regard your persons? saith the LORD of hosts. Who is there even among you that would shut the doors for nought? neither do ye kindle fire on mine altar for nought. I have no pleasure in you, saith the LORD of hosts, neither will I accept an offering at your hand. For from the rising of the sun even unto the going down of the same my name shall be great among the Gentiles; and in every place incense shall be offered unto my name, and a pure offering: for my name shall be great among the heathen, saith the LORD of hosts. But ye have profaned it, in that ye say, The table of the LORD is polluted; and the fruit thereof, even his meat, is contemptible. Ye said also, Behold, what a weariness is it! and ye have snuffed at it, saith the LORD of hosts; and ye brought that which was torn, and the lame, and the sick; thus ye brought an offering: should I accept this of your hand? saith the LORD. But cursed be the deceiver, which hath in his flock a male, and voweth, and sacrificeth unto the Lord a corrupt thing: for I am a great King, saith the LORD of hosts, and my name is dreadful among the heathen.
Their offering was not Holy,it did not fear God,unfortunately the Priests accepted the offering which was wrong,God did not accepted thus Robbed
Its like today,the scriptures says we are offer our "First Fruit" in our Tithes
but sometimes we give our leftover wages or none at all,confessing "God understands"
As a full Gospel believer of Jesus Christ we are to keep Gods commandments
