It is a Bible doctrine with continuity in the Scriptures, before, during, and after Moses Law.
The tithe is not mine to withhold; it belongs to the Lord (Leviticus 27:30).
Tithing is an indicator of faithfulness to God (2 Chronicles 31:12).
Tithing is an indicator of our generosity (2 Chronicles 31:5). And A generous man will himself be blessed (Prov. 22:9).
Tithing allows God-called ministers to devote themselves fully to the Lords work (Numbers 18:21; 1 Corin. 9:13f).
I dont want God to consider me a robber (Malachi 3:8).
God wants His house, the church, to be abundantly supplied (Malachi 3:10 with 1 Timothy 3:15).
God says if we are faithful in tithes & offerings, He will open the windows of heaven and pour out abundant blessings (Malachi 3:10-12; also Proverbs 3:10).
We are honoring the Lord when we give to Him (Prov. 3:9).
There is a bible principle of sowing and reaping (2 Corin. 9:6). As we sow generously, we shall reap generously, both naturally and spiritually.
