Psalms 28:6

6.Blessed be Jehovah, who hath heard. This is the second part of the psalm in which the prophet begins to give thanks to God. We have already seen how he employed himself in prayer in the midst of his dangers; and now by this thanksgiving he teaches us that his prayers were not in vain. Thus he confirms by his own example, that God is ready to bring help to his people whenever they seek him in truth and sincerity. He declares the same truth more fully in the next verse, calling God his strength and his shield; for he was persuaded that God had heard him from this, that he had been wonderfully preserved. He adds, that he had been helped in respect of his confidence and hope; for it often comes to pass, that those who call upon God, notwithstanding come short of his grace through their own unbelief. Thirdly, he says that he will add to his joy a testimony of his gratitude. Wicked men and hypocrites flee to God when they are overwhelmed with difficulties, but as soon as they escape from them, forgetting their deliverer, they rejoice with frantic mirth. In short, David trusted not in vain, since he truly found by experience that God possesses ever present power to preserve his servants; and that this was matter of true and solid joy to him, that he found God ever favorable to him. On this account, likewise, he promises that he would be mindful of God, and grateful to him. And undoubtedly, when God spreads cheerfulness through our hearts, it is to open our mouths to sing his praises.
