My wife and I plant a small garden each year. They are just a few small beds with tomatoes, zucchini, peppers, strawberries and a few other things; but we enjoy the fresh produce it brings and the joy of seeing it grow.
But, I don't enjoy the weeding and the watering it requires if we have a dry spell. I'd rather the Lord provide rain (at night if possible) so that I can skip the watering (and save money too).
In my devotional today I read from Jeremiah 17 which says, "Blessed is the one who trusts in the Lord, whose confidence is in him. They will be like a tree planted by the water that sends out its roots by the stream. It does not fear when heat comes; its leaves are always green. It has no worries in a year of drought and never fails to bear fruit."
If we are constantly having to seek nourishment from ourselves (self help books, meditation, yoga, darkness retreats like the one that Aaron Rogers just went on...), we will always be thirsty; but if we can plant ourselves near the stream of living water...then we will never thirst and never run dry.
