(A man giving his shoes to a homeless girl)
Sometimes Christians get turned off with doing good because those they are helping are taking advantage of them or are being lazy or are spending money foolishly. Or, those they help whine and complain instead of being grateful and thankful.
Sometimes Christians think they don't have the time. It takes away from my work. It takes away from my leisure. It takes away from my family.
Regardless of the situation or the circumstances, Paul's advice to us is this: "Let us not become weary in doing good." Keep on helping, keep on ministering, keep on serving, keep on doing the Lord's work.
"Let us not become weary in doing good." Look at doing good as a privilege. If you keep reminding yourself that it is a privilege to serve the Lord, you are not likely to become weary in doing good. Say to yourself, "God has chosen me to be His servant." And be amazed at the wonder of this.
The image here is of a farm. If there is one worker who knows what it means to stay on the job, it is the farmer. He must prepare the soil, sow the seed, pull the weeds, and water the plants. He can never afford to give up or quit. Regardless of the long hours, the heat of the sun, or the cold of the rain, he must keep on working. And in spite of all this he has no guarantee of reaping a harvest.
The farmer has no guarantee of the harvest, but the Christian worker does have a guarantee. God promises a harvest to those who not give up on doing good. God promises a harvest to those who do not become weary in doing good.
