Good day y'all today the 20 April, 2021, this is my response to the above question.
Firstly Brother Eli stated vividly that they is no difference between Malachi 3:7-10 and 2 Corin 9:7. Prov 8:8kjv: "All the words of my mouth are in righteousness; there is nothing froward or perverse in them".
Tithe: It is an obligation given to us by God. Num 18:26kjv: "Thus speak unto the Levites, and say unto them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the Lord, even a tenth part of the tithe". Tithe is 10% of our proceeds.
Offering: Offering is also an obligation given by God to us. Deu 16:16b,17kjv: "and they shall not appear before the Lord empty: Every man shall give as he is able, according to the blessing of the Lord thy God which he hath given thee". Offering are gift from our heart, it is also to humanity. 2 Corin 9:6-7kjv: "But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully. Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver".
Should we give Tithe or Offerings ?
Yes, it is an obligation from God. Mala 3:10kjv: "Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the Lord of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it".
