Charles H. Spurgeon on Psalms 5:11

Joy is the privilege of the believer. When sinners are destroyed our rejoicing shall be full. They laugh first and weep ever after; we weep now, but shall rejoice eternally. When they howl we shall shout, and as they must groan for ever, so shall we ever shout for joy. This holy bliss of ours has a firm foundation, for, O Lord, we are joyful in thee. The eternal God is the well-spring of our bliss. We love God, and therefore we delight in him. Our heart is at ease in our God. We fare sumptuously every day because we feed on him. We have music in the house, music in the heart, and music in heaven, for the Lord Jehovah is our strength and our song; he also is become our salvation.
