In Mark 4:28, Jesus said, “The soil produces crops by itself; first the blade, then the head, then the mature grain in the head.” In other words, after planting seeds, the harvest comes in stages. That’s true naturally and it’s also true spiritually.
For example, many times healing comes gradually over a process of time. That’s not only true of healing, that’s also true concerning every other area of faith.
I think that people often quit in the initial stages of the harvest. They get a little harvest and they’re so excited, they’re satisfied with just that. But God wants you to go on and believe for “the mature grain in the head”. He wants you to get an abundant harvest of whatever you’re believing for!
