" . . . Everyone who keeps from defiling the Sabbath, and holds fast My covenant--even them I will bring to My holy mountain, and make them joyful in My house of prayer. . . . "
Here (above) is a sweet promise to the faithful churchman. Do you love the Lord? Do you love Him enough to value His Sabbath (Sunday), His church, and His worship? If so, then there are real solid blessings that are yours. You will know "mountain" experiences of praise (even in this world); and you will be joyful in God's house, His church.
Most religious people are seeking their fulfillment in other places, and in other ways. They may receive some false "highs" from time-to-time; but only the faithful get the real goods (in Christ). Stay the course of faith--you will not regret it (on the last day).
[Puritan quote of the day: "Prayer is the pouring out of the soul to God; not the pouring out of words, nor the pouring out of expressions; but the pouring out of the soul to God." --William Bridge, in "A Lifting Up for the Downcast"]
