Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? But I trust that ye shall know that we are not reprobates. Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates. For we can do nothing against the truth, but for the truth. For we are glad, when we are weak, and ye are strong: and this also we wish, even your perfection. Therefore I write these things being absent, lest being present I should use sharpness, according to the power which the Lord hath given me to edification, and not to destruction.
2 Corinthians 13:5-10
the power
…That I may know Him…
But what things were gain to me, those I counted loss for Christ. Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ, and be found in Him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith: that I may know Him, and the power of His resurrection, and the fellowship of His sufferings, being made conformable unto His death; if by any means I might attain unto the resurrection of the dead.
Philippians 3:7-11
