"It is not genuine consecration to think that we can refuse to be used of God now in order to store up our spiritual power for later use. That is a hopeless mistake. The Spirit of God has set a great many people free from their sin, yet they are experiencing no fullness in their lives— no true sense of freedom. The kind of religious life we see around the world today is entirely different from the vigorous holiness of the life of Jesus Christ. “I do not pray that You should take them out of the world, but that You should keep them from the evil one” (John 17:15). We are to be in the world but not of it— to be separated internally, not externally (see John 17:16)."
We are already filled to the fulness with God's Power:
"Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ:" (Ephesians 1:3)
and
"I thank my God always on your behalf, for the grace of God which is given you by Jesus Christ;
"That in every thing ye are enriched by him, in all utterance, and in all knowledge;" (1 Corinthians 1:4-5)
and
"[H]is divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:" (2 Peter 1:3)
