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.
Believers understand why the world seems completely oblivious to its true need. Yes, the world needs peace but not the peace they suspect – absence of war! Bible students recognize that trusting Jesus Christ is the means whereby individuals can quench their thirst for peace. This knowledge of the truth carries with it a grave responsibility along with a marvellous privilege. The scripture points to the beauty of the feet of those that “bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth!” Why are the feet mentioned as being so beautiful? The feet of the man carry him to publish peace. Similar phraseology appears in Nahum 1:15. Those who know God's peace are blessed with the responsibility and granted the opportunity to take that message of peace to others.
Christians should first and foremost focus on their walk with the Lord. As such, believers are instructed to add virtue, knowledge, temperance, patience, godliness, brotherly kindness, and charity to their faith. However, notice that every believer is to be “giving all diligence” (with great effort, but without haste). Of all these graces mentioned, faith seems to be the most foundational of them all. Unfortunately, far too many believers never grow beyond faith, making them unable to put forth much diligence in adding the other graces. Believers should be growing in grace daily (like those listed above) and in the knowledge of our Lord and Saviour (2 Peter 3:18). The word of God remains the only viable source from whence this diligent growth springs forth (1 Peter 2:2).
