It can be frustrating.
Serving. Giving. Investing. Volunteering. Risking. Sacrificing. Forgiving. Persisting.
With no visible return. With no tangible "fruit." With no immediate results.
Sometimes you just want to stop.
But, you can't.
If a "harvest" is what you want, a "seed" is what you'll need.
If you want the "harvest" of a healthy body, a passionate marriage, disciplined kids, good grades, thriving leaders, a fulfilling career, committed disciples, a profitable business, a strong organization, etc...
You are going to need to plant the "seeds" of time, effort, energy, work, consistency, showing up, love, long-suffering, practice, etc...
There's no harvest without the seed.
Don't grow weary. Keep planting.
