Jesus also said, “The Kingdom of God is like a farmer who scatters seed on the ground. Night and day, while he’s asleep or awake, the seed sprouts and grows, but he does not understand how it happens. The earth produces the crops on its own. First a leaf blade pushes through, then the heads of wheat are formed, and finally the grain ripens. And as soon as the grain is ready, the farmer comes and harvests it with a sickle, for the harvest time has come.” (Mark 4:26-29 NLT)
We find the first specific example of tithing in Abram’s visit to Melchizedek in Genesis 14. It would be great if we could find the tithe specifically mentioned in the life of Isaac as well, but we can’t. We do know that he learned a great deal about covenant life from his father. In Genesis 26 we find him in the land of the Philistines and in the midst of a famine. His go-to plan is the great principle of the Kingdom: sow seed. and reap a harvest. The result is a harvest so great that the Philistines are jealous. I believe he learned how to get a crop even in famine from living in plenty with Abraham. He learned to pay his crop insurance.
