“Therefore be ye perfect, even as your Father in heaven is perfect.”
The Spirit is perfection, therefore you are called to be perfected by the Spirit. The verse says “by one sacrifice he has perfected forever those who are being made holy”.
Therefore the perfection of the Spirit dwells in those who are in the process of being perfected.
It is the Spirit who reveals the wonder of God’s plan for us, who brings to us the reality of death having been removed from our future. When taken by faith, this truth is that which expands our consciousness into his consciousness, and reveals the splendour of HIM.
