We need give ourselves no trouble about the reward of our life. Be it ours only to do our duty faithfully, sweetly, lovingly, all the days; then God will see that we do not miss the reward of fidelity. Our Lord suggests that the righteous will be surprised at the Judgment to learn of the glory and greatness of the services of love they have rendered to needy ones. Supposing only that they were showing kindness to the poor, they will learn that they were serving the King himself. Thus the smallest and obscurest ministry will flash out in splendid radiancy in the day of final revealing. No true service done in this world in Christ's name will fail of blessing and reward. Even the acts which seem to have been of no avail will leave a benediction somewhere. If your kind word or deed blesses no other, the doing of it will bless your own heart. Though your effort do no good to the one you meant to help, it may touch another life. Our wayside seed-sowing is not lost.
Proverbs 19:17: He that hath pity upon the poor lendeth unto the LORD; and that which he hath given will he pay him again. (KJV)
Ecclesiastes 11:1: Cast thy bread upon the waters: for thou shalt find it after many days. (KJV)

Matthew 25:34-40: Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? When saw we thee a stranger, and took thee in? or naked, and clothed thee? Or when saw we thee sick, or in prison, and came unto thee? And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me. (KJV)
2 Corinthians 9:6-11: But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully. Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver. And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work: (As it is written, He hath dispersed abroad; he hath given to the poor: his righteousness remaineth for ever. Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness;) Being enriched in every thing to all bountifulness, which causeth through us thanksgiving to God. (KJV)

Hebrews 6:10: For God is not unrighteous to forget your work and labour of love, which ye have shewed toward his name, in that ye have ministered to the saints, and do minister. (KJV)
