When you do not pay your tithes, you rob God, and immediately step into an area that allows Satan to send additional problems. God permits these problems to come your way because of disobedience. Some of the things you may see can be loss of work, loss of health, famine, scarcity, unreasonable weather, insects to eat the fruit of the land, or money losing much of its value. The end result is that you will become spiritually and physically poor. You have been demonstrating your lack of love for the Lord by your disobedience to His Word, in your tithing, because John 14:15 tells you, "If you love Me, keep My commandments."
Malachi 3:8 Will a man rob God? Yet you have robbed Me! But you say, "In what way have we robbed You?" In tithes and offerings. 9You are cursed with a curse, for you have robbed Me, even this whole nation
