No. The verse behind that fear was spoken to Israel under the Law, not to you under the New Covenant. You give because you're loved and free, never to avoid a curse.
The Grace Answer
The fear in this question usually traces back to one verse, quoted from a pulpit with a warning attached: “Will a man rob God?” It lands like a threat. Give, or you are stealing from the Almighty. But that verse was never aimed at you.
Malachi was speaking to a specific people, under a specific covenant, about a specific system. The tithe funded the Levitical priesthood and the temple of national Israel. It came with blessings for keeping it and curses for breaking it, because that is how the old covenant worked. It was a legal arrangement, and the law always ran on that engine: perform, and be blessed; fail, and be cursed.
That engine died at the cross. You are not under a system of blessing-for-performance and curse-for-failure. The only curse Scripture leaves for the believer is the one Christ already absorbed: “Christ has redeemed us from the curse of the law, having become a curse for us.” There is no curse left hanging over your bank account.
So why give at all?
Because giving was never meant to be extraction. Under grace, generosity flows from a heart that already has everything. You give the way a loved child shares, not the way a tenant pays rent. Paul set the tone in one sentence: give what you purpose in your heart, not grudgingly or under compulsion, because God loves a cheerful giver. Compulsion and cheerfulness cannot occupy the same act. The moment giving becomes a debt you owe to stay safe, it has stopped being grace.
This is freer, not looser. A believer who understands that God already gave them everything in Christ tends to become wildly generous, not stingy. But it comes from rest, not fear. You are not robbing God by keeping your money. You could not rob a Father who already handed you the whole estate.
