Kefa 1 / 1 Peter 2:4-6 Amplified Bible (AMP)
Called As Living Stones
4 Come to Him [the risen Lord] as to a living Stone which men rejected and threw away, but which is choice and precious in the sight of God.5 You [believers], like living stones, are [a]being built up into a spiritual house for a holy and dedicated priesthood, to offer spiritual sacrifices [that are] acceptable and pleasing to God through Jesus Christ. 6 For this is contained in Scripture:
“Behold, I am laying in Zion a chosen stone, a precious(honored) Cornerstone,
And he who believes in Him [whoever adheres to, trusts in, and relies on Him] will never be disappointed [in his expectations].”
(When YAHUSHUA our MASHIACH was on earth, HE was a Jew who) “wore TZITZIT, ate KOSHER, celebrated PASSOVER, kept the SHABBAT (SABBATH) and obeyed the TORAH!” We believe in doing the same.
As ABBA YAHUVEH / YAHWEH (GOD THE FATHER) says in the TORAH, it will be a sign between you and ME (Shemoth / Exodus 31:13, 17 and Ezekiel 20:12, 20), “ (keeping the Sabbaths)” It pleases GOD (YAH) very much when we obey HIM faithfully.
It is a sign that we belong to YAH!
