To say that tithes or offerings is what gives financial prosperity or causes open heavens totally negates the message of GRACE.
Remember, to receive by grace means it's unmerited and undeserved.
God has blessed us freely and he wants us to equally bless freely.
Ko gb'owo, ko gb'obi
Ko gba nkankan lowo mi
Ko to damisi o
Ko gba nkankan l'owo mi
He didn't take any money, yet no offering
He didn't take anything from me
Before God blessed me
He collected NOTHING from me.
Freely receive and therefore freely give.
THE JUST SHALL LIVE BY FAITH.
