The one who sows to the Spirit will from the Spirit reap eternal life - Galatians 6:8
Planting out seeds is an act of faith: faith that something will grow; faith that what grows will grow well; and faith that what grows well will end up looking something like the picture on the packet. There are no instant results in gardening, and certainly not in farming. Fields sown with Asparagus will take years to produce a decent crop, and patience needs to grow alongside the crop.
There is a similar pattern in the spiritual life. You can try and build a habit of prayer, but grow discouraged because you can see no results after a month or so. You can set aside a little while each day to read your Bible, but find the practice still feels dry a few weeks in. What is the point?
In the end it is often patience we lack, rather than effort. Stickability is a spiritual discipline to set alongside our daily routines. Foolish indeed would be the farmer who re-ploughs the field after a week because shoots cannot be seen. More foolish the Christian who gives up praying before God answers.
