"Present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service" (Romans 12:1)
The offering and the sacrifice and the sanctifying energies of the Holy Spirit are indeed sufficient to prepare the soul for communion with God. This the Bible declares and this ten thousand times ten thousand witnesses confirm.
The big danger is that we assume that we have been delivered from our sins when we have in reality only exchanged one kind of sin for another. This is the peril that lies in wait for everyone. It need not discourage us nor turn us back, but it should make us watchful.
We must, for instance, be careful that our repentance is not simply a change of location. Whereas we once sinned in the far country among the swineherds, we are now chumming with religious persons, considerably cleaner and much more respectable in appearance, to be sure, but no nearer to true heart purity than we were before.
In the deeper experience of a sanctified heart, there must be another conviction, not of sin, but of sinfulness, before the soul is ready to receive the Holy Spirit and the abiding presence of the Lord.
