"Blessed are they whose ways are blameless, Who walk according to the Law of the Lord." (Psalm 119:1) [Psalm 119 is an acrostic with every letter of the Hebrew alphabet representative of our divine walk in 8 verses each.]
The first letter is Aleph (the Ox) which is a gentle animal raised for service and used for blood sacrifice. Jesus also was raised as a young man to grow strong for service, his life ending in the ultimate blood sacrifice.
It is by Jesus' sacrifice that we are blameless, and in following in the footsteps of Jesus --through his truth, his spirit and his grace that we are blessed.
