Tithing is an important subject and provides a direct solution to the OPs dilemma.
Ive shared this many times before on this forum, but Ill say it again since many of you never read it.
Tithing started with Abraham. Abraham was the Father of Faith, and existed long before Moses. It can also be argued that Cain and Abel were the first in the Bible to tithe and give of their substance. One of the major differences between the two brothers offerings was that Able gave God his best, and Cain didnt. In our case, 10% of one's gross pay is our best. God gets the first cut before Uncle Sam. The Law of Moses only clarified the principle of honoring God with our substance, and giving back what belongs to Him, so that his kingdom can flourish and the gospel could be spread throughout the world. Tithing is a spiritual law. How churches spend the money today is another matter altogether. Its easy to worship God with our lips, but giving him of our substance is an act of worship and obedience. Actions speak louder than words, and God is not fooled by our lying tongues and deceitful hearts
In one of the 4 gospels, Jesus praised a poor woman in the temple who gave 2 pence in the offering, because she gave everything she had, as opposed to a rich man who gave out of his abundance.
Here, the Apostle Paul is justifying that ministers are given the right to live off the peoples tithes and offerings:
1Corin. 9:[13]- Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the alter are partakers with the alter? [14] Even so hath the Lord ordained that they which preach the gospel should live of the gospel.
If the people dont tithe, how would full time ministers live?
Consider this- Why would the most quoted scripture on tithing in the Book of Malachi be the last book of the Old testament, after which the Lord did not move and work on the Earth for the next 400 years before the coming of Jesus? Who then would the Book of Malachi benefit?
Regarding Jews,
Romans 2: [28] For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:[29] But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
Romans 10:[12] For there is no difference between theJew and the Greek: for the same Lord over all is rich unto all that call upon him.
Galations 3: [28] There is neitherJew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
To imply that only blood Jews are required to obey Gods spiritual laws is in error. And, to say that the Laws in the old testament do not apply is like saying I can murder and commit adultery, because were not subject to the Ten Commandments (Old Testament) anymore.
There are certain practices in the letter of the Old Testament we don't have to follow anymore because they are of a spiritual nature, like shedding lamb's blood for the remission of sins, and eating unleavened bread, etc.. But money is money, and if you don't tithe, how then is it fulfilled in the Spirit?
