You might argue that ‘everyone belongs.’ And they do.
Before the cross all of humanity belonged as a sons of God. Notionally. Post cross everyone belongs due to the at-one-ment – the enterprise of the trinity in drawing us into the reality and fellowship of God’s life. Life in God, although there is but one God is life in the community of the trinity.
‘For in him we live and move and have our being.' As some of your own poets have said, 'We are his offspring’ Acts 17.28 NIV.
We belong in spirit and in truth – which is to say we belong as a state of being because we agree with God that our person is one with God. We belong by putting our faith in the real Christ who is the Christ of God along with adhering to the real Gospel that is the gospel of Jesus, Paul and John. Because we have not accepted a false christ and a self-generated gospel we belong in spirit and truth and not just notionally. Our heart knows that we belong when our heart knows the truth: That we and our Father are one. There is an identity to be had as sons and daughters of the new covenant that the heart of the old covenant Believer does not enjoy. Because it remains in separation. We are one with God in spirit and in truth when Christ is our life. We remain in self imagined separation from God when we remain in Adam.
Stan Grant wrote on the ABC website about the issue that is the issue of our age: Identity. You can have an identity as Christian. You can draw an identity from your denomination. Or you can find yourself in the only place in which you are an authentic you: In the Christ of God and in the state of being in which you and our Father are one. As God says in the book of James. You can have but one master. Grant writes of the lesser identities that suffocate life and kill love.
A mistaken identity forges a crippled person. A mistaken gospel creates a community of cripples. This is why we have one husband who is Christ and one Christ who has His own gospel..
“It is identity forged out of resentment and a thirst for vengeance. It is identity that draws its narrative from the old festering hatreds of history. It is identity that pits us against each other; that divides us into our tribes. It is a 21st-century law of the jungle: something deeply primal; that leads us to tear each other limb from limb. Look around our world, we are putting up new walls; we are militarising our borders; we fear the stranger and retreat into old certainties and closed communities.”
Actually it’s not identity that does all this. It’s mistaken identity and misplaced identity that denies us the comfort of God and genuine community with each other.
