One of the greatest preachers of the 20th century, Martyn Lloyd-Jones, identifies the twin truths the church must come back to, namely, that Christians are the children of God and partakers of the divine nature.
“…until we come back to this and really understand this and feel it and experience its power, I see no hope for the Church.”
There is surely no greater honour and no greater dignity that can ever come into our ken or comprehension than just this, that we have upon us the name of God. It is not surprising that John, in the prologue of his Gospel, puts it like this: that to ‘as many as received him gave he the power (the right, the authority) to become the children of God’ (1:12). There is nothing beyond that, nothing conceivable beyond that, that we are actually members of God’s own family. This is literally the truth about us as Christians. John again says, ‘Beloved, now we are the children of God’ (1 John 3:2). We do not know what we shall be in fulness, he goes on to say, but we do know that this is what we are already, now, the children of God. The apostle Peter is equally concerned about it and says that we are ‘partakers of the divine nature’ (2 Peter 1:4). More and more it seems to me that it is our failure at this point that really explains why the Christian Church is as she is. And it does not matter what we do or try to do; until we come back to this and really understand this and feel it and experience its power, I see no hope for the Church. We are the children of God, partakers of the divine nature itself.[God’s Way of Reconciliation, An Exposition of Ephesians (Grand Rapids, MI: Baker Books, 1971), 330]
