1Ki 17:7 And it happened after a while that the brook dried up, because there had been no rain in the land.
In the first year of the draught, God for the sake of His servant Elijah reserved a brook that refreshed him in addition to the daily supply of bread and meat he received. Elijah was in the receiving end and resting, but after a while, the brook dried up because there was no rain due to draught.
In order for faith to grow, seasons are bound to change or else faith remains stagnant. In agriculture, a seedbed is a plot of land, well prepared where seeds and young plants are aided with special care in order to grow before being transplanted. The worst thing the agriculturalist can do for the plants is to leave them in the seedbed past their required time, for it would hinder or stunt their growth. Elijah for our sake was in a seedbed where everything he needed for the growth of his faith was provided for. God knew when he outgrew the seedbed. The message here is this, many times we operate in the same place sometimes for a long time, and what was to be temporary we turned it into permanent. Think of the times you have been in a job, ministry for many many years. It served well but now you can tell that your faith though still there stopped growing. As long as the ravens and the brook continued to supply, it was easy to stay the same in the seedbed. In order for our faith to grow and mature, moving may sometimes be forced by brooks drying up.
