Charles H. Spurgeon on Psalms 89:16

In thy name shall they rejoice all the day. And good cause they have for so doing, for to the soul which, in Christ Jesus, has entered into covenant with God, every attribute is a fountain of delight. There is no hour in the day, and no day in our life, in which we may not rejoice in the name, person, and character of the Lord. We need no other reason for rejoicing. As philosophers could make merry without music, so can we rejoice without carnal comforts; the Lord All sufficient is an all sufficient source of joy. And in thy righteousness shall they be exalted. By the Lord's righteous dealings the saints are uplifted in due time, however great may have been the oppression and the depression from which they may have suffered. In the righteousness which the covenant supplies, which is entirely of the Lord, believers are set on high in a secure and blessed position, so that they are full of sacred happiness. If God were unjust, or if he regarded us as being without righteousness, we must be filled with misery, but as neither of these things are so, we are exalted indeed, and would extol the name of the Lord.
