. . . Whatsoever man there be . . . among you, that offereth . . . And bringeth it not unto the door of the tabernacle of the congregation, to offer it unto the Lord ; even that man shall be cut off from among his people. Leviticus 17:8-9 KJV
The tithe is Holy to the Lord. It belongs to God the minute you receive increase. It is not yours, it is His.
The tithe and offering are to be presented in the house of the Lord. This requires your presence.
Much blessing is available to those who are faithful, thankful, and cheerful givers.
Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the Lord of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it. And I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast her fruit before the time in the field, saith the Lord of hosts. And all nations shall call you blessed: for ye shall be a delightsome land, saith the Lord of hosts. Malachi 3:10-12 KJV
The windows of heaven are opened to you.
The blessings of God will shower upon you.
The devourer will be rebuked by the Lord Himself
Your harvest (income) will not fail.
The nations will call you blessed.
You shall be delightsome.
So, present your self to Him in church each Sunday and give Him what is rightfully His.
