James 5:7-8

So wait patiently, brothers and sisters, until the coming of the Lord.  The farmer waits (expectantly) for the precious harvest from the land, being patient about it, until it receives the early and late rains.  You too, be patient strengthen your hearts (keep them energized and firmly committed to God), because the coming of the Lord is near. 

The farmer does a lot of preparation before planting the seed into the ground, just as faith produces what it believes for, like a seed with an expectant harvest to come in due season.  We, too, must practice patient and planting of our faith like a seed, so it grows and strengthens.  So that when uncertain times come, we have a firm foundation knowing that the coming of the Lord is near and we have nothing to fear.
