'Sacred' in the Bible

remember that at that time you were separated from Christ [excluded from any relationship with Him], alienated from the commonwealth of Israel, and strangers to the covenants of promise [with no share in the sacred Messianic promise and without knowledge of God’s agreements], having no hope [in His promise] and [living] in the world without God.

in whom the whole structure is joined together, and it continues [to increase] growing into a holy temple in the Lord [a sanctuary dedicated, set apart, and sacred to the presence of the Lord].
