"It is tragic that many believers become entangled in a quest for something more in the Christian life, for something special, something extra that the "ordinary" Christian life does not possess. They talk of getting more of Jesus Christ, more of the Holy Spirit, more power, more blessings, a higher life, a deeper life--as if the resources of God were divinely doled out one at a time like so many pharmaceutical prescriptions or were unlocked by some spiritual combination that only an initiated few can know.
To say, 'I want to get all of Jesus there is,' implies that when we were saved Christ did not give us all of Himself, that He held some blessings in reserve to be parceled out to those who meet certain extra requirements.
Peter explicitly says, 'His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence' (2 Peter 1:3). The New Testament teaching of salvation is that the new birth grants every believer everything in Christ. There is consequently no need and no justification in searching for anything more." (Dr. John MacArthur, The MacArthur New Testament Commentary: Ephesians, 41).
