Mal 3:10 Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the LORD of hosts, if I will not open the windows of heaven for you and pour down for you a blessing until there is no more need.
In Malachi 3:10, Israel is depicted as thinking that their offerings have no affect on the world. God, to reverse this, challenges Israel to challenge Himself. Malachi 3:10 falls in the context of the famous prooftext for immutability (Mal 3:6). In contrast to immutability, the context is God’s dynamic relationship to Israel. God states that if Israel repents, then He will respond. Verse 10 is very explicit about the open nature of the future and God’s possible responses. God tells Israel to test Him, not knowing if they will or will not. He implies that He will pass their tests and give them blessings as a result. Israel, as evident in the question, is skeptical of God. God wishes to reach the people through a give and take relationship.
