It’s beneficial to be Believers in Jesus’ Story rather than some alternative story. Remember that the Father of lies was able to precipitate the fall by suggesting a seemingly plausible alternative narrative of existence, Fatherhood and sonship. Plausible it may have been but it was a lie and as such it was a seed of disintegration and death.
If there is a principle to observe it is that separation from God brings degradation, disease and death while relationship and union with God is life, joy, love and well-being. It follows that any gospel that subtracts from what God has done in Christ or adds to it, has the same effect.
If the insinuations of the Enemy about Father, ourselves and our nature were debilitating so are assumptions that weaken Christ’s gospel and render it ineffective by distorting and diluting it into another variety of the knowledge of good and evil.
Thomas Torrance writes,
“Just as there is ‘one Lord’, ‘one baptism’ and ‘one faith’, so there is ‘one body’. They [these] are central to the Church’s confession of faith in the Holy Trinity and cannot be treated as affirmations having significance in themselves apart from their integration with the substance of the evangelical and apostolic kerygma.” (1)
What is this ‘apostolic kerygma? It is the core of the gospel, the undiluted doctrine of Jesus and the apostles. Torrance is saying there is one authoritative gospel, not several and as such one genuine Body of Christ and not a collection of zombie bodies put together like Frankenstein collections of bones and flesh.
Our belonging to the genuine Body of Christ is dependent on our belonging to the genuine gospel of Christ and the apostles teaching. This will determine if we are living in healing and resurrection or terminal decay.
