Malachi 3:6-18 NLT
6 “I, the Lord, never change. That is why you descendants of Jacob haven’t been destroyed yet.
7 Since the time of your ancestors you have turned away from my laws and have not followed them. Return to me, and I will return to you,” says the Lord of Armies. “But you ask, ‘How can we return?’
8 “Can a person cheat God? Yet, you are cheating me! “But you ask, ‘How are we cheating you?’ “When you don’t bring a tenth of your income and other contributions.
9 So a curse is on you because the whole nation is cheating me!
10 “Bring one-tenth of your income into the storehouse so that there may be food in my house. Test me in this way,” says the Lord of Armies. “See if I won’t open the windows of heaven for you and flood you with blessings.
11 Then, for your sake, I will stop insects from eating your crops. They will not destroy the produce of your land. The vines in your fields will not lose their unripened grapes,” says the Lord of Armies.
12 “All nations will call you blessed because you will be a delightful land,” says the Lord of Armies.
13 “You have used harsh words against me,” says the Lord. “You ask, ‘How have we spoken against you?’
14 “You have said, ‘It’s pointless to serve God. What do we gain if we meet his standards or if we walk around feeling sorry for what we’ve done?
15 So now we call arrogant people blessed. Not only are evildoers encouraged, they even test God and get away with it.’”
16 Then those who feared the Lord spoke to one another, and the Lord paid attention and listened. A book was written in his presence to be a reminder to those who feared the Lord and respected his name.
17 “They will be mine,” says the Lord of Armies. “On that day I will make them my special possession. I will spare them as a man spares his own son who serves him.
18 Then you will again see the difference between righteous people and wicked people, between the one who serves God and the one who doesn’t serve him.
The verse 18 concludes between the righteous people and wicked people, and between the one who serves God and the one who doesn’t serve God. Here, the tither is considered righteous and is serving God.
The faithfulness of bringing back the tithes and offering unto God is the acknowledgement that all the blessings are from God. We can do nothing without Him thus we must honor Him with the tithes and offering. And in these, God will continue to bless us and protect us.
But those who don’t bring back the tithes and offering are thieves and wicked people though they claimed they are Christians, they are actually counterfeit whom also called pretenders.
