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.
Joy and peace! Any sensible person would readily admit his desire for a life filled with joy. Yet, few people understand the prerequisites for regularly living that way. Previous studies mentioned several of joy’s accompanying virtues, but today’s passage provides one of joy's unifying properties. According to our passage, peace accompanies joy. Proverbs 12:20 also expresses this same relationship: “Deceit is in the heart of them that imagine evil: but to the counsellors of peace is joy.” Those who seek peace will often find joy in this life because peace and joy are entwined. Isaiah 55:12 restates this truth: “For ye shall go out with joy, and be led forth with peace.” It is important to note that men will not “go out with joy” unless they are first “led forth with peace.” Peace and joy are always inseparable. Those who have the peace of God after they are at peace with God through salvation will experience "joy unspeakable" (1 Peter 1:8).
