For as the new heavens and the new earth, which I will make, shall remain before me, saith the Lord, so shall your seed and your name remain.
And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the Lord.
(Isaiah 66: 22-23)
Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ. (Colossians 2: 16-17)
