The Spirit Does Not Contradict the Gospel

But in promising it, of what sort did he declare his Spirit would be? One that would speak not from himself but would suggest to and instill into their minds what he had handed on through the Word [John 16:13]. Therefore the Spirit, promised to us, has not the task of inventing new and unheard-of revelations, or of forging a new kind of doctrine, to lead us away from the received doctrine of the gospel, but of sealing our minds with that very doctrine which is commended by the gospel. ~ Institutes of the Christian Religion

The Gospel is Not a Doctrine of the Tongue

“The gospel is not a doctrine of the tongue, but of life. It cannot be grasped by reason and memory only, but it is fully understood when it possesses the whole soul and penetrates to the inner recesses of the heart.”
