Charles H. Spurgeon on Psalms 16:2

"My goodness extendeth not to thee; but to the saints." God's goodness to us should make us merciful to others. It were strange indeed a soul should come out of his tender bosom with a hard uncharitable heart. Some children do not indeed take after their earthly parents, as Cicero's son, who had nothing of his father but his name; but God's children all partake of their heavenly Father's nature. Philosophy tells us, that there is no reaction from the earth to the heavens; they indeed shed their influences upon the lower world, which quicken and fructify it, but the earth returns none back to make the sun shine the better. David knew that his goodness extended not unto God, but this made him reach it forth to his brethren. Indeed, God hath left his poor saints to receive the rents we owe unto him for his mercies. An ingenuous guest, though his friend will take nothing for his entertainment, yet, to show his thankfulness, will give something to his servants. —William Gurnall.
