Bible and abundant harvests

I was just reading this book "One Word from God Can Change Your Life by Kenneth and Gloria Copeland" and I came across these few bible verses that spoke about how we are able to receive abundant harvests. 

The following verses will give much clarity and the main focus of receiving is on giving. :)

Commonly heard quotes: "Give and you will receive"

Give, and you will receive. Your gift will return to you in full - pressed down, shaken together to make room for more, running over, and poured into your lap. The amount you give will determine the amount you get back.

Luke 6:38

Commonly heard quotes: "God loves a cheerful giver"

Remember this - a farmer who plans only few seeds will get a small crop. But the one who plants generously will get a generous crop. You must each decide in your heart how much to give. And don't give reluctantly or in response to pressure. "For God loves a person who gives cheerfully". And God will generously provide all you need. Then you will always have everything you need and plenty left over to share with others.

2 Corinthians 9:6-8

Commonly heard quotes: "Reap what you sow"

Don't be misled - you cannot mock the justice of God. You will always harvest what you plant. Those who live only to satisfy their own sinful nature will harvest decay and death from that sinful nature. But those who live to please the Spirit will harvest everlasting life from the Spirit. So let's not get tired of doing what is good. At just the right time we will reap a harvest of blessing if we don't give up. Therefore, whenever we have opportunity, we should do good to everyone - especially to those in the family of faith. 

Galatians 6:7-10

"Bring all the tithes into the storehouse so there will be enough food in my Temple. If you do," says the LORD of Heaven's Armies, "I will open the windows of heaven for you. I will pour out my blessing so great you won't have enough room to take it in! Try it! Put me to the test! Your crops will be abundant, for I will guard them from insects and disease. Your grapes will not fall from the vine before they are ripe," says the LORD of Heaven's Armies. "Then all nations will call you blessed, for your land will be such a delight," says the LORD of Heaven's Armies.

Malachi 3:10-12
