Power in praise. Harvest of gold. Reading Psalms, Proverbs, Jude

The title and opening verses of Psalm 92 suggest that the pattern for Sabbath worship is to gather together for corporate worship both morning and evening: “A Psalm or Song for the sabbath day. It is a good thing to give thanks unto the LORD, and to sing praises unto thy name, O most High: To show forth thy lovingkindness in the morning, and thy faithfulness every night” (Ps. 92:1-2). In the Bible..., “evening and morning” stand for the whole day (e.g., Gen. 1:5). The practice of beginning and ending the Sabbath in corporate worship shows that the entire day belongs to God.

In Genesis chapter 2 we read:
1 Thus the heavens and the earth were finished, and all the host of them.

2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.

3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.

You will notice that God blessed the seventh day (the Sabbath) and sanctified it. Sanctified means set apart for holy use. This was done at creation.
