The Lord warned His followers about the wickedness of those who have an inordinate desire to be in authority over others. “The princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon them” (Matthew 20:25). The people of God should not be controlled by such men (or women). Those who know and love the Lord should sincerely desire to serve others rather than to be in authority over them. The chief example is the Lord Jesus Christ who “came not to be ministered unto, but to minister, and to give his life a ransom for many” (Matthew 20:28). John gave a similar warning when he spoke of “Diotrephes, who loveth to have the preeminence” (3 John 1:9).
Believers should seek to be pure in every facet of life. One might consider limiting this to the places he goes or the things he hears and sees, but purity demands a much greater focus. Believers ought to think on pure things (Philippians 4:8) with pure minds (2 Peter 3:1) and pure consciences (1 Timothy 3:9; 2 Timothy 1:3). In particular, believers should have pure hearts before the Lord (1 Timothy 1:5; 2 Timothy 2:22). A pure heart will lead to a pure conscience and a pure mind. A pure heart changes where a man goes, what he looks upon, and the things he allows to enter into his ears. Every Christian should strive to make sure that all things are pure.
