John 19:31-37 (especially verse 36)
Bones in the Old Testament (and in OT Hebrew
thinking) are part of the soul/life of a person, a family, a friendship, a body
of people (like the nation of Israel, or the Church the Body of Christ, or - I
think - the whole people or kingdom of God (as in: "you are my flesh and
bone", or "bone and blood", or other variations).
Our bones knit us together (make us whole,
one, united). Our bones make us whole in the sense of making us strong, or able,
or properly functional.
The Passover Lamb, as a sacrifice, and as the
basis of the Passover meal, is a mediator, and a promise, and a bond on the journey from Egypt to the Promised land, from slavery to freedom. The Lamb represents God, and
God's promises (as being strong, and well tied together, and complete) for the journey. The Passover Lamb represents Israel/God's people (including the Church), who are an offering to God as one
body, and one soul for the journey.
Jesus is the wholeness of God coming to us, and the wholeness of us, ourselves, including all of God's beloved people and
creation.
Jesus is (incarnates) the offering of
Israel, and of the house of David, and of the whole of the Church: offering to
God the wholeness that we cannot give to God because of our fallenness.
In Christ our self-giving will be whole,
entire, perfect, strong, fully functioning; and this will be fulfilled in us
when God finishes his work of making a new heaven and earth. But we can have some connection with this in our lives now.
It represents how we stand before God and
each other in faith, hope, and love.
In the end, we can count on God's promise that we will not be broken, just as Christ remained unbroken for us. Sometimes, by the Lord's grace and gift, we can experience being held within this promise now.
Brother! Thank you for asking about the bone and the unbroken bones in the Bible, because it's an issue that we Christians do not deal with very consistently or thoroughly. Usually, we deal with these issues from different "pivot points" than through "the bones".
