"If you want to know the power of God (that is, the resurrection life of Jesus) in your human flesh, you must dwell on the tragedy of God. Break away from your personal concern over your own spiritual condition, and with a completely open spirit consider the tragedy of God. Instantly the power of God will be in you. “Look to Me. . .” (Isaiah 45:22)."
We have no reason whatsoever to be concerned about our "own spiritual condition" -- Christ is taking care of us.
In the Old Testament, the prophets, priests, and kings had to look out for God, and look to themselves to live holy lives. That's why David pined:
"Cast me not away from thy presence; and take not thy holy spirit from me." (Psalm 51: 11)
Following the Finished Work of Jesus, there is no longer need for propitiation for sins:
"We are sanctified through the offering of the body of Jesus Christ once for all." (Hebrews 10: 10)
The Holy Spirit enters us, never to leave again:
"Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
"So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me." (Hebrews 13:5-6)
We no longer have to look out for Him, but recognize with the "eyes of our understanding" that He is in us, doing and ever increasing and infinitely mighty work (Ephesians 1:17; 2:10)
