One of the most exciting things I ever discovered about God's law of sowing and reaping was the fact that financial harvests are not seasonal. If you plant year round, you can be receiving year round.
Don't misunderstand. I'm not saying your harvest will come instantly. It usually won't. You may have to wait for it for several months. What I'm saying is, if you'll keep planting consistently, you'll receive just as consistently. If you'll continually cast your bread on the water, eventually it will come in on every wave!
Of course, some people never get to enjoy that kind of constant blessing. That's because, instead of giving, they keep waiting to receive. They stand on the beach saying, "I wonder where my prosperity is? As soon as it comes in, I'll start giving."
