Are you sowing financial seed but failing to reap the harvest that God says you are entitled to? You can sow seed, and give your tithe consistently; however, according to the Word, it doesn't matter how much you give, if there is offense in your heart, your sowing won't bear fruit.

This could be the very answer you've been looking for as to why you are sowing much but reaping little. It's time to get the offense out. Offenses not only affect your growth in the Lord, your success in life, and your destiny, but they also have a direct effect on your finances.
And now art thou cursed from the earth, which hath opened her mouth to receive thy brother's blood from thy hand; When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth.
(Gen. 4:11-12)
We saw in the story of Cain and Abel that because of an offense, Cain's life began to dry up. He was offended, and his life was no longer fruitful. He was a wanderer, a vagabond, continually going here and there and never bearing fruit in his life.

Do you believe we are in the time of supernatural increase and restoration? I believe we are, and God wants us to reap the full potential from our giving.
And those sown on good (well-adapted) soil are the ones who hear the Word and receive and accept and welcome it and bear fruit - some thirty times as much as was sown, some sixty times as much and some [even] a hundred times as much.
(Mark 4:20 AMP)
Now the Word of God says that if you sow seed you're going to receive a thirty, sixty or a hundred fold return. Carolyn didn't write it. So why aren't we receiving that kind of harvest on every seed that we sow? It could be because of an insult or an offense that we've held in our hearts towards someone who hurt us.
And when ye stand praying, forgive, if ye have aught against any: that your Father also which is in heaven may forgive you your trespasses. But if ye do not forgive, neither will your Father which is in heaven forgive your trespasses.
(Mark 11:25)
God is plainly revealing to us that unforgiveness can hinder our prayers from being answered. Your behavior can stop your harvest from manifesting. Aught in this context can be defined as "a grudge, resentment, bitterness or malice." If you are holding a grudge against someone, then the Father can't forgive you.

Malice is defined as "deep-seated animosity, hostile feelings, ill-will wished upon another or bitterness." Can you identify with these feelings? If so, then that would explain why your harvest has been stopped. You cannot expect God to multiply your seed and increase you financially if you are holding a grudge against someone. It doesn't matter how bad they hurt you, you will not go forward in life until the offense is removed.

Bitterness in your heart is like a root that goes down deep. It can't just be pulled up one time. You have to keep an eye on it. You have to dig down deep into your spirit and vigorously work at getting that root of bitterness out. It's the same thing in a garden. You have to work hard at pulling roots up, especially weeds.

Well, bitterness is like a weed, and if you don't keep manicuring your garden (heart), then those weeds will come up automatically without you even noticing it. Weeds just appear overnight. They grow so fast and eventually can crowd out the other plants.

Don't let the root of bitterness crowd out the good fruit in your life. You have the fruit of the spirit abiding on the inside of you which is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, and temperance.

You will have the opportunity to be offended every day, but you have to make a quality decision to not let anyone offend you. Start digging up those weeds. You may have weeds that need to be pulled out from an insult that occurred twenty years ago. Well, start digging.
You have sown much, but you have reaped little; you eat, but you do not have enough; you drink, but you do not have your fill; you clothe yourselves, but no one is warm; and he who earns wages has earned them to put them in a bag with holes in it.

Thus says the Lord of Hosts: Consider your ways (your previous and present conduct) and how you have fared.
(Haggai 1:6-7 AMP)
According to Haggai, if you are sowing much and reaping little, then you need to consider your ways. Not God's ways. Obviously, there is something about your life that needs to be changed. It could be that you are offended. Ways is defined as "course of action, methods and manners, conduct and behavior." In other words, if you are sowing much, but reaping little, then it's time to consider your behavior. Your behavior has a profound effect on the kind of harvest you receive.
You have heard that it was said to the men of old, You shall not kill, and whoever kills shall be liable to and unable to escape the punishment imposed by the court.

But I say to you that everyone who continues to be angry with his brother or harbors malice (enmity of heart) against him shall be liable to and unable to escape the punishment imposed by the court; and whoever speaks contemptuously and insultingly to his brother shall be liable to and unable to escape the punishment imposed by the Sanhedrin, and whoever says, You cursed fool! [You empty-headed idiot!] shall be liable to and unable to escape the hell (Gehenna) of fire.

So if when you are offering your gift at the altar you there remember that your brother has any [grievance] against you, Leave your gift at the altar and go. First make peace with your brother, and then come back and present your gift. Come to terms quickly with your accuser....
(Matt. 5:21-25 AMP)
We have found the answer to why we sow much and reap little. It's us. We've got to release all bitterness from our hearts. Do you believe we are in the end time? Do you believe that time is speeding up and we don't have much time left here on planet earth? I believe that we only have a few years left. If that is in fact true, then God is going to speed up the sowing and reaping process so we can finance the Gospel to the world. We've got to have the finances to publish the Gospel to all nations so we can bring Jesus back. So, let's not allow offenses in our heart to stop the sowing and reaping process in our lives. We've got work to do. We've got to share Jesus with others.

Determine to forgive those who have trespassed against you no matter how minor or how severe the attack was. Don't allow their insult to effect your harvest. Release all offenses in your life that are keeping you in bondage and are hindering the return on your giving that the Lord wants you to receive.
