Then as the buckets fill, they are emptied into large bins that sit over an open fire. The sap comes to a slow boil; and as it boils, its water content is reduced and its sugars are concentrated. Hours later, it has developed a rich flavor and golden-brown color, but it must be strained several times to remove impurities before being reheated, bottled, and graded for quality. In the end, those 30-40 gallons of sap are reduced to one gallon of pure, delicious maple syrup, which is far better than the cheap, imitation, colored sugar-water that passes for maple syrup in the grocery store.
So it is when we come to faith in Christ. We start like raw, unfinished sap, which could have been tossed aside as worthless. But God knew what he could make of us. He sought and found us, and his skillful hands are transforming us into something precious, sweet and useful. The long and often painful refining process brings forth a pure, genuine disciple easily distinguished from cheap imitations.
