Charles H. Spurgeon on Psalms 35:27

"Let them shout for joy, and be glad, that favour my righteous cause." Even those who could not render him active aid, but in their hearts favoured him, David would have the Lord reward most abundantly. Men of tender heart set great store by the good wishes and prayers of the Lord's people. Jesus also prizes those whose hearts are with his cause. The day is coming when shouts of victory shall be raised by all who are on Christ's side, for the battle will turn, and the foes of truth shall be routed. "Yea, let them say continually, Let the Lord be magnified." He would have their gladness contributory to the divine glory; they are not to shout to David's praise, but for the honour of Jehovah. Such acclamations may fitly be continued throughout time and eternity. "Which hath pleasure in the prosperity of his servant." They recognised David as the Lord's servant, and saw with pleasure the Lord's favour to him. We can have no nobler title than "servant of God," and no greater reward than for our Master to delight in our prosperity. What true prosperity may be we are not always best able to judge. We must leave that in Jesus' hand; he will not fail to rule all things for our highest good.

"For by his saints it stands confessed.

That what he does is always best."
