When one accepts the Lord Jesus as their Savior they are now apart of the Kingdom of God. They are now children of God living in this world but not of this world. They are set a apart, peculiar.
Our wealth and riches and health are tied to the Kingdom of God, not the earth or the economic system. The Kingdom of God operates in sowing in reaping. He who sows sparingly with reap sparingly. He who sows bountifully will reap bountifully.
Malachi 3: 8-11 KJV states;
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. 11 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. 12 And all nations shall call you blessed: for ye shall be a delight some land, saith the Lord of hosts.
When we give Lord the tithe, 10%, we giving to God what is required according to His kingdom principles. We are required to pay taxes to the government, right? We should also pay the tithes to the Lord. In paying the tithe, the Lord is saying He will bless us with what we need and more. In order for God to bless us, He has to get us to give what is in our hands.
When we give the Lord what is due to him, he also stops the evil one from stealing from us. He will make us fruitful. Then He says all nations will call us blessed! Wow, so by following the kingdom principles set by God, paying tithes will cause God to bless me. Wow! That is good news!
