Mark 4:29 – But when the fruit is brought forth, immediately he putteth in the sickle, becausethe harvest is come. 

As a child of the most high God, you have a right to harvest your seed. And when you tithe, that portion is holy which makes your 90% holy and protected by God. It’s His covenant promise to you!
Oral Roberts said, the problem with most Christians is that they leave their harvest in the field.
So how do you prevent this from happening? You receive by faith by speaking the Word over your seed and stand until it manifests in your life. How long does will this take? As long as it takes. Just stand in faith and believe you receive.

Don’t believe you’re going to receive it, believe you’ve already received it by faith.
