Psalms 100:1,2

Make a joyful noise unto the Lord Partly, with voices, and songs of rejoicings, and thanksgiving; and partly with musical instruments, as the manner then was; all ye lands That is, all the inhabitants of the earth. When all nations shall be discipled, and the gospel preached to every creature, then this summons will be fully obeyed. Serve the Lord with gladness Devote yourselves to, and employ yourselves in, his service. Come before his presence with singing In the ordinances which he has appointed, and in which he has promised to manifest himself to his people. In all acts of religious worship, whether in secret or in our families, we may be truly said to come into God's presence; but it is in public worship especially that we enter into his gates, and into his courts, as expressed Psalms 100:4, which should be with thanksgiving for so great a privilege, and with praise for his goodness manifested herein.
