That God’s method of financing His work of spreading the Gospel is by the tithes and offerings of His people through the New Testament church. Tithing was instituted before the law, and by Christ in the New Testament.
MATTHEW 23:23
23 Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
LEVITICUS 27:28-34
28 Notwithstanding no devoted thing, that a man shall devote unto the Lord of all that he hath, both of man and beast, and of the field of his possession, shall be sold or redeemed: every devoted thing is most holy unto the Lord.
29 None devoted, which shall be devoted of men, shall be redeemed; but shall surely be put to death.
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.
31 And if a man will at all redeem ought of his tithes, he shall add thereto the fifth part thereof.
32 And concerning the tithe of the herd, or of the flock, even of whatsoever passeth under the rod, the tenth shall be holy unto the Lord.
33 He shall not search whether it be good or bad, neither shall he change it: and if he change it at all, then both it and the change thereof shall be holy; it shall not be redeemed.
34 These are the commandments, which the Lord commanded Moses for the children of Israel in mount Sinai.
1 CORINTHIANS 16:1-2
16 Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye.
2 Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
LUKE 6:38
Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.
2 CORINTHIANS 9:6-15
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
8 And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
9 (As it is written, He hath dispersed abroad; he hath given to the poor: his righteousness remaineth for ever.
10 Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness;)
11 Being enriched in every thing to all bountifulness, which causeth through us thanksgiving to God.
12 For the administration of this service not only supplieth the want of the saints, but is abundant also by many thanksgivings unto God;
13 Whiles by the experiment of this ministration they glorify God for your professed subjection unto the gospel of Christ, and for your liberal distribution unto them, and unto all men;
14 And by their prayer for you, which long after you for the exceeding grace of God in you.
15 Thanks be unto God for his unspeakable gift.
GENESIS 14:17-20
17 And the king of Sodom went out to meet him after his return from the slaughter of Chedorlaomer, and of the kings that were with him, at the valley of Shaveh, which is the king's dale.
18 And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God.
19 And he blessed him, and said, Blessed be Abram of the most high God, possessor of heaven and earth:
20 And blessed be the most high God, which hath delivered thine enemies into thy hand. And he gave him tithes of all.
MALACHI 3:7-10
7 Even from the days of your fathers ye are gone away from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith the Lord of hosts. But ye said, Wherein shall we return?
8 Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings.
9 Ye are cursed with a curse: for ye have robbed me, even this whole nation.
10 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.
2 CORINTHIANS 8:1-8
8 Moreover, brethren, we do you to wit of the grace of God bestowed on the churches of Macedonia;
2 How that in a great trial of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality.
3 For to their power, I bear record, yea, and beyond their power they were willing of themselves;
4 Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints.
5 And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God.
6 Insomuch that we desired Titus, that as he had begun, so he would also finish in you the same grace also.
7 Therefore, as ye abound in every thing, in faith, and utterance, and knowledge, and in all diligence, and in your love to us, see that ye abound in this grace also.
8 I speak not by commandment, but by occasion of the forwardness of others, and to prove the sincerity of your love.
